Incompatibility with Java 9 - JRE Path changed #304
Comments
Looks like this just needs a small change at https://github.com/kivy/pyjnius/blob/master/setup.py#L82 , but I'm not sure exactly what should be different (e.g. is this a new condition if |

Hi @inclement, I'm just coming back to this now. Was this feedback enough to make an update? |
Guys, any update ? |
It's not just an OSX issue if you're using open-jdk the jre folder no longer exists. Any open jdk version >= 9 no longer has the jre folder. See http://openjdk.java.net/jeps/220 since java 9 the folder hierarchy was restructured. The jre/lib/amd64/server/libjvm.so path is no longer valid ( Line 163 in 1cbfef2

That bug will also affect the usage of Java >= 9 using the soon-to-be-released conda-forge builds: conda-forge/openjdk-feedstock#34, conda-forge/openjdk-feedstock#35, conda-forge/openjdk-feedstock#36 |
kivy/pyjnius#304 needs to be fixed to use OpenJDK >8
Fixed in #363 |
Pyjnius 1.1.4 requires to unset DYLD_LIBRARY_PATH with JRE 1.8 regardless if the value is correct or not. While not backwards compatible it is good not to have to care about it in the environment any more. |
@rhoerbe Could you please link some official documentation/changelog why this change happened. I'm curious if it has other implications for the whole system and not Java only. |
The issue occurred within the Pycharm IDE in a rather bulky project that is not suitable to isolate the issue. When creating a separate demo-repo I was unable to reproduce it. Now I am a few commits ahead, and changed the Django-settings, and cannot reproduce the issue in my main project any more. There are a couple of combinations to test to reproduce - I gave up. What I can describe is that downgrading pyjnius from 1.1.4 to 1.1.3 fixed the issue. However, to reproduce it there seem be other factors than JRE 1.8 and DYLD_LIBRARY_PATH. |
PyJnius looks for the path
/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/jre/lib/server/libjvm.dylib
but the
jre
folder doesn't exist in this hierarchy anymore and it should look for/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/lib/server/libjvm.dylib
