Java applications running with JDK6 or older can produce windows 1 pixel high / wide #705

totaam · 2014-10-06T03:49:03Z

Attached is a very simple test case.

export JAVA_HOME=/opt/jdk1.6
$JAVA_HOME/bin/javac Main.java 
$JAVA_HOME/bin/java Main

Click on the button and the dialog window appears correctly, close it and try again and it gets mapped as a 1 pixel high window..

I have tested many versions of Java, including the IBM SDK, opensdk, Sun's SDK, etc..
This only affects Java 6 and earlier. (which is the version supported in centos 5 and some centos 6 installations..)

r7959 added CreateNotify support for X11 event logging since the window seemed to be configured wrong by the time we get notified.

logging window creation the first time (correct - summary):

Reconfigure on withdrawn window (190,70)

second time around (buggy):

Found a potential client
new window 0xa0002c

client configured window 6 - WindowModel(0xa0002c - " "), at: (0, 0, 1, 1)

So the problem occurs very early on, when we read the window's initial dimensions.
It looks like Java is caching something (in one of its numerous hidden event windows?) which causes the new dialog window to inherit the wrong size. During a reparent maybe?
This obviously does not happen with other window managers, so we must be doing something wrong.

This ticket was originally recorded as a JOGL bug - but as can be seen in the example code, that was wrong, JOGL has nothing to do with it.

The text was updated successfully, but these errors were encountered:

I have also tried:

using Xvfb or Xvnc as X11 servers, no change - same bug
using Xnest with and without a window manager (ie: twm): no bug
diffing xwininfo -root -tree first and second run (no significant change)

So... that leaves tracing the X11 calls done by twm and comparing with xpra's. Oh joy.

Interesting: by killing (kill -9) the xpra server at various points and doing the other steps from a shadow copy with no window manager running, I have narrowed down the problem to the mapping of the initial 2 windows:

if xpra maps the main window and the dialog window at least once, the bug will occur afterwards, even with twm or no window manager
if xpra only maps just the main window, or the just the first dialog window but not the main window, the bug does not occur!

I also found a ticket which looks very similar: JOSM starts as few pixel width window. - but the resolution does not apply here.

Which can be translated as (verbs are as seen from the application context):

create normal input/output window 0x00600029 named " " of size 200x71 which is a child of the root window 0x00000025 (it will be referred to as the "main window")
create normal input/output window 0x0060002f named "sun-awt-X11-XIconWindow" of size 16x16 as a child of 0x00600029
set WM_HINTS and WM_NORMAL_HINTS on the main window
create normal input/output window 0x00600030 named "Content window" of size 200x100 as a child of the main window
map "Content Window"
create input only window 0x00600032 named "FocusProxy" of size 1x1 as a child of the main window
create normal input/output window 0x00600033 named "sun-awt-X11-XButtonPeer" of size 1x1 as a child of the "Content Window"
MapWindow the "sun-awt-X11-XButtonPeer" (and the MapNotify is duly received) - all still at size of 1x1, once mapped it is configured (and the configure notify is duly received) for the same position and size as the main window (its parent)
request that the main window is configured to be on top (stack above)
request MapWindow the "main window"
the main window is reparented into 0x004000a5 (presumably twm's frame) at (0,29)
the main window is configured above-sibling 0x004000a5, and with the same position (2,31) and dimensions (200x71) as before
the main window is mapped and its WM_STATE" is set to normal
query the window attributes and geometry on 0x004000a5 (its size is 200x100, it is Viewable, etc)
update the main window's normal hints

totaam · 2014-10-31T12:47:03Z

with xpra it does this:

create normal input/output window 0x00800019 named " " which is a child of the root window 0x00000044 (this is the "main window")
no XIconWindow window is created... (and I don't think we care about that - at least not for this bug, we'll see if window icons are missing with Java apps later)
set hints (as above)
create normal input/output window 0x0080001b named "Content Window" of size 200x100 as a child of the main window above
create the FocusProxy (0x0080001d)
create the XButtonPeer (0x0080001e)
map the button peer (as above)
request that the main window is configured to be on top
request MapWindow the "main window"
the main window is configured, but above-sibling is not set... (not honoured - we have no code for this)
the main window is reparented into 0x0040012c, at (0,0) - we explicitly set it to (0,0) as the coordinates are meant to be relative?
the main window is mapped and its WM_STATE is normal
query the window attributes and geometry on 0x0040012c: its position is (0,0) still, is is Viewable, its size is OK (200x71) ..
odd configures event are seen for the main window: width=0, height=0 ! (maybe a response to the stack request?, which may have zero width and height.. or something)

Some of the configure requests aren't honoured, and some of those don't make much sense!

Need to investigate:

honour stack-mode in ConfigureWindow
when reparenting, preserve position instead of setting it to 0,0
fix missing ConfigureNotify and weird dimensions..

Attacking this from different angles:

JDK versions:
after testing more JDK versions, openjdk6 builds do not have this problem! (tested with java-1.6.0-icedtea-1.13.2.x86_64 built from source using the icedtea SRPM)
So there must be a fix in icedtea / openjdk which solves this bug (relevant link: What is the difference between JVM, JDK, JRE & OpenJDK?). It is a rather large patch set unfortunately, and we don't have the source for the buggy Sun SDK...
No problems either with java-1.5.0-gcj.

Since there are a few tricks in the Java source code based on the window manager name, I added r8025 which allows us to easily set it (_NET_WM_NAME on the ewmh window). Alternatively, wmname could be used for testing.
I've tried a few of them (LG3D, Sawfish, Compiz) and this did not help.

I've also tried setting: AWT_TOOLKIT=MToolkit - no change (wasn't really expecting it to work since we are a reparenting window manager), it did cause crashes with some of the window manager names. (in catgets called from GetAllProtocolsMgr - whatever this is, probably because it is not expecting us to reparent)
Useful information on this subject can be found here: [http://awesome.naquadah.org/wiki/Problems_with_Java]

This looks like it could be related: [http://bugs.java.com/bugdatabase/view_bug.do?bug_id=6632124] and [http://bugs.java.com/bugdatabase/view_bug.do?bug_id=6429775], but we do set _NET_FRAME_EXTENTS as early as we can already.
Also found a good reference for focus events: Java 6 Focus Spec.

Logging from the Java side:
create a logging.properties file with java.util.logging.ConsoleHandler.level = FINE in it
run the example code with:

java -Djava.util.logging.config.file=./logging.properties Main |& tee log

Then stripping the date+time from the debug output with:

sed -r 's/^.*:[0-9][0-9] //g' < log nodate.log

And comparing the buggy one (sun jdk -) with the working version (openjdk +), I see:

quite a few "containing window" get logged because opensdk lacks disposing = false at the end of the line...
XConfigureEvent also logged because it includes the sun.awt.X11.XFramePeer object address...
when creating the dialog, opensdk logs: reparented: false - so it looks like there is code in there to deal with reparenting..

Looks like something is calculating based on the screen size, and getting it badly wrong!

diff between broken and working debug log

Found this in the Java patch nomotif-6706121.patch - worth a read:
''
Unfortunately the concept of "insets" borrowed to AWT from Win32 is absolutely, unbelievably foreign to X11. Few WMs provide the size of frame decor (i.e. insets) in a property they set on the client window, so we check if we can get away with just peeking at it. [Future versions of wm-spec might add a standardized hint for this].''

-Otherwise we do some special casing. Actually the fallback code ("default" case) seems to cover most of the existing WMs (modulo Reparent/Configure order perhaps?).*

-Fallback code tries to account for the two most common cases:*

''single reparenting
parent window is the WM frame
[twm, olwm, sawfish]''
''double reparenting
parent is a lining exactly the size of the client
grandpa is the WM frame
[mwm, e!, kwin, fvwm2 ... ]''

This code is absolutely horrible, no wonder they refactored it in JDK 7!
See also JDK bug 4304985: Frame opening fails to restore location

I think what is happening is that the code checks for the parent size, finds it is the same as the window (because we don't have any window decorations on the server!) and assumes that the real window frame has to be the grand parent... which is the root window, and it is huge which causes the crazy large inset calculations.

Setting the window manager as Sawfish seems to fix this problem!
(makes Java assume single-reparenting behaviour)

Run xpra as of r8033 (will backport the important bits):

XPRA_NET_WM_NAME=Sawfish xpra start ...

Keeping this ticket open as we may want to find a cleaner solution, one that does not involve lying about our window manager name!

updated test class which also dumps information about the graphics context

Backport in 8061. Closing.

r8065 makes it easier to verify that the workaround is in place, ie:

$ XPRA_NET_WM_NAME=Sawfish xpra start
$ xpra info | grep window-manager-name
window-manager-name=Sawfish

We query it at runtime to catch changes made externally using tools like wmname.

Improvements in r8329 + r8330, backported in 8333.

added config file option (easier when testing)
set the name on the root window (since "wmname" doesn't check properly and looks it up there, other apps probably make the same mistake)
