OOM in reactor build and javac
------------------------------

         Key: MNG-1503
         URL: http://jira.codehaus.org/browse/MNG-1503
     Project: Maven 2
        Type: Bug
  Components: maven-compiler-plugin  
    Versions: 2.0    
 Environment: Windows JDK 1.4.2
    Reporter: mike perham


We are seeing a OOM error when running a medium-sized reactor build (approx 15 
projects).  After about 10 modules, the javac plugin fails with an OOM in a 
module that actually has just a single java file.  Forking the VM actually 
leads to an immediate error in the first module so I assume forking does not 
work currently.

Setting the max heap memory by using set MAVEN_OPTS=-Xmx512m has no visible 
effect.


The system is out of resources.
Consult the following stack trace for details.
java.lang.OutOfMemoryError
