Maven build OutOfMemoryError Chunck::new

Question

I get an error every time I try and build a small project (our sdk). I have set my MAVEN_OPTS to -Xms1024m -Xmx1536m and I have a 6-12 GB of swap on both of my hard drives (so 24 GB total). I have 6 GB of physical ram on my box of which 4 GB is allocated... so I really don't think I should be getting this error! When I build my main project I get an OutOfMemoryError as well, but when I build again it completes the build. This project will not complete. Any help?

OS Info:

I don't know if it's the root of your problem, but -Xmx sets max memory. Set it higher. If it's set too low, you can get OutOfMemory exceptions. And keep Xms small as it may add to the problem.

Furthermore, take a peek at those hints, may prove useful:
