Re: [epp-dev] [ptp-dev] Parallel Package (Juno Win32) Error 'Failed to create the Java Virtual Machine' - on Windows
Hmm, thanks for the Mr. package... but I don't know a real solution.

The current settings with 2GB are in place since Juno SR1 (see bug 389517) and I agree that this seems a bit high.

In the .product file this can be set for all platforms or for specific platforms only (i.e. restricted to linux, macosx, windows), but it is *not* possible to restrict it to an architecture (e.g. x86 or x86_64). It might be possible to specify it in this granularity in the p2.inf file, but I never tried to add this kind of argument there.

One solution could be to remove these VM arguments from the 'all platforms' section, and apply individual settings to the different platforms like the example below. Note that I chose a different, lower value for windows.

   <launcherArgs>
      <programArgs>-product org.eclipse.epp.package.parallel.product
--launcher.defaultAction openFile</programArgs>
      <programArgsWin>--launcher.XXMaxPermSize
256M</programArgsWin>
      <vmArgs>-Dosgi.requiredJavaVersion=1.5
-Dhelp.lucene.tokenizer=standard</vmArgs>
      <vmArgsLin>-XX:MaxPermSize=256m
-Xms512m
-Xmx2048m</vmArgsLin>
      <vmArgsMac>-XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts
-XX:MaxPermSize=256m
-Xms512m
-Xmx2048m</vmArgsMac>
      <vmArgsSol>-Xms512m
-Xmx2048m</vmArgsSol>
      <vmArgsWin>-Xms512m
-Xmx1024m</vmArgsWin>
   </launcherArgs>

If I were you I'd try to use a lower value, e.g. the 1024 MB, instead of the 2024 MB for all platforms. I believe that users are used to modify this value in the eclipse.ini if they are running into out-of-memory, heap, etc. errors, but users are not familiar with an application that doesn't start at all. In my opinion that's the worse case and leads to a very bad first impression.

Regards,
Markus

In the product file, can't you specify memory settings by platform so win32 could get bumped down, but all others would remain at 2048m?

    Is this only for the win32 package, or for all architectures? I would rather have win32 failing than all the other architectures failing with out of memory errors.

      Markus, we are seeing several win32 testers not being about to launch on WinXP win32 without bumping down the
      eclipse.ini -XMX value
      We didn't see this in the previous release (SR1)

      I just bumped it down in epp.product from  the default -xmx 2048 to 1024, maybe we need 768, but i notice that cpp's is even lower, 512m.
      Advice???  
      Lower might be safer so at least new users can bring it up.  an OutOfMemoryException later would lead you to increase it later, at lease.

      What do you think?

      I also commented on the bug, I can get it to run with 512m and 1024m for -Xmx, I think it's just a memory allocation request compared to what the machine actually has available. The default is 2048 (kinda high for a 32 bit machine which can only utilize 4gb max).
