Darin:
Can you isolate a particular java program that causes this out of memory
exception?  Are there a lot of files to troubleshoot?

It works fine on 1.4.1_07
I have only a certain set of VMs that I can get my hands on due to 
restrictions imposed by my employer :-) so I cannot get 1.4.1_02 or 
1.4.1_03

I was testing on 1.4.2_03. and 1.4.2_04; both fail.

Hi Darin.

I don't have your answer however I'm curious if your problem works fine
on 
1.4.1_02 and does not work on 1.4.1_03.

Thanks NetaB...but I don't think you helped me at all :-)

I have fork set to be true so memorymaximumsize and memoryinitialsize 
should not be ignored.

The main thrust of my question is why the difference running on the two 
implementations of javac? 
Works fine on 1.3.1, 1.4.1. 
Does not work on 1.4.2? 
I could not find a bug in Sun's bug parade either for this problem with 
javac.

TIA
Darins

Hi Darin,
Did you try to run ant with ANT_OPTS set to something like: -Xms1024m
-Xmx1024m
When you pass the flags  memorymaximumsize and memoryinitialsize it is
only used when you set the compiler to run on new JVM and
Is deprecated when you use your default javac.

Subject: Out of memory with javac

Ant 1.6.1

Running the same buildfile I am seeing different results for using javac
depending on the javac executable I am using.

<javac fork="true" debug="on" memoryinitialsize="200m"

memorymaximumsize="200m" destdir="testingBin" classpath=...> </javac>

Using a 1.4.2 JDK install,  I always run out of memory when the task is
forked and I set memory attributes....and it is not that big of a build.
[javac] The system is out of resources.
[javac] Consult the following stack trace for details.
[javac] java.lang.OutOfMemoryError

Using a 1.3.1 JDK install, exact same buildfile, no out of memory.

It is almost like the -J options passed to the 1.4.2 javac.exe are
ignored?

Is this a known issue? I searched bugzilla but found nothing new enough
to be relevant Is this just dumb user error :-) ?

TIA
Darins
