> The surefire report plugin fails to create a test report with an 
> OutOfMemoryError. 
> I've set MAVEN_OPTS to -Xmx512m and to -Xmx1024m. With 512m the report fails 
> after about 3 minutes, with 1GB it taks significantly longer. Both report 
> generation tasks fail.

> This happens regardless of the actual JUnit tests - I ran this with 
> -Dmaven.test.skip=true.
> The target/surefire-reports directory contains over 700 MB of XML reports, 
> mainly due to long stack traces in the mostly failing 2000+ tests. However 
> the JUnit reports plugin in ANT which we used to use had no problems handling 
> this kind of data.
