OOM error while building latest trunk

Thu, 16 Apr 2009 06:53:22 -0700

I consistently faced the following error while building latest trunk and to work around, I had to set MAVEN_OPTS=-Xmx512m in my environment. Is it because there are just a lot of things getting built in the same reactor requiring more memory? 

Thanks,
