Thanks Steve! That was indeed the issue. Now I know my code coverage! Much appreciated.

Thanks. That's most likely my issue. I got pulled away from that branch onto some critical work, but will let you know when I can try your fix.

Sometimes the instrumentation and reporting can eat a lot of memory if there are too many classes to instrument. The documentation on mojo states that the cobertura:cobertura target does the following: Instruments, Tests, and Generates a Cobertura Report. This means it executes the test maven target for you. The reason I say it's an issue with surefire is because if you executed cobertura:instrument or cobertura:report you probably won't see the exception, however only during the execution of the tests will you see the error which indicates it's an issue with the jvm from surefire.

Add this to the surefire section: <argLine>-Xmx2048m</argLine> That hopefully should resolve the issue. Thanks, Steve.

The test do use a significant amount of memory. When I run them on there own (using Maven and the surefire plugin), I they require approximately 2 GB to run (i.e. No memory issues occur if I use –DargLine="-Xmx2048"). I set up the maxmem property in an active profile my settings.xml like so: <profiles> <profile> … <properties> <cobertura.maxmem>2048M</cobertura.maxmem> </properties> </profile> </profiles> And would expect my tests to pass when I do this: mvn cobertura:cobertura But I get an out of memory error. Even if I set the max memory usage to 8 GB, I get that error. I am guessing that this has something to do with the way that cobertura manages memory, but know so little about it. Can anyone provide some guidance? Thanks!
