grunt "minall" step fails with Error: Could not create virtual machine. (Solution found, unsure about PR)

[benlesh]

All steps outlined for building the Angular project would work right up until I ran grunt package. At that point it would run until it made it to the "minall" task and it would fail.

Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Problem discovered

Upon further investigation I went into lib/utils.js and had grunt.log print out the shell command it was executing to run closure.jar against each file.

The command that was being run was:

java -Xmx2g -cp bower_components/closure-compiler/compiler.jar;bower_components/ng-closure-runner/ngcompiler.jar org.angularjs.closurerunner.NgClosureRunner --compilation_level SIMPLE_OPTIMIZATIONS --language_in ECMASCRIPT5_STRICT --minerr_pass --minerr_errors build/angular-sanitize-errors.json --minerr_url http://errors.angularjs.org/undefined/ --source_map_format=V3 --create_source_map build/angular-sanitize.min.js.map --js build/angular-sanitize.js1--js_output_file build/angular-sanitize.min.js

At that point I was given the message(s):

Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Apparently my 32-bit JVM on Windows 7 does not like allocating 2gb of space. I'm not sure why, because AFAIK, 2gb is the maximum heap size value.

Workaround

When I changed -Xmx2g to -Xmx512m everything worked fine and I was able to build.

Question(s)

• Given the nature of how this JVM is being used, is 2GB max heap really necessary, or can it be reduced to 512MB?
• Should this be handled in the java32flags() function in utils? In other words, if it's a 32 bit JVM should the max heap flag be reduced, whereas 64-bit JVM could state the same?

... either way I'm glad I finally got past this issue at least locally.

Same issue here.

This bug was run into on one of my separate repositories which uses the closure compiler as well, and we were able to solve it by the mechanism suggested here:

When I changed -Xmx2g to -Xmx512m everything worked fine and I was able to build.

I thought there was already a patch implementing this, but maybe I'm mistaken

edit I guess #4831 wasn't merged yet... hmm

I guess they aren't sure about merging it because they aren't positive 512mb would be enough for the closure compiler to work on the library. It's hard to say --- but since people with 32bit JVMs seem to be able to build Angular with that setting, and not with the higher setting, it's probably okay, is it not?

[benlesh]

Well, something needs to be done, I inadvertently committed that change to utils.js in a PR. It was caught, fortunately, but still. It seems like maybe an automated check or something could be done? I'm not sure.

Fix: Install 64-bit JVM

1. Install the 64-bit version of Java 7 SE
2. Close whatever consoles you have open (PowerShell, CMD, etc)
3. Update your PATH variables: Remove C:\Program Files (x86)\Java\jre7\bin (the 32-bit version) and add: C:\Program Files\Java\jre7\bin (the 64-bit version)
4. Reopen your console app and try grunt package again

Don't worry about installing 32-bit and 64-bit Java side-by-side

They work together just fine. In fact, you can even have multiple version of Java (6 and 7 for example) installed side-by-side. No worries.

blesh , Thanks!

Tried that solution, after switching to 64-bit Java (Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)) I have

I have Win7 x64, 8GB RAM.

As I understand, the only workaround is to apply this change: MJRichardson@51e3290 ?

@Blesh yes, it also solved my problem on mac by installing java 64bit for mac.
