Hi,
If I built more than 1.5k files, I receive crash with Out of memory error. I'm trying to make a custom representation of project, but when around 1k files are built, progress speed is reduced, processor starts reserving 90-100%. The first thing you may think is advising to increase memory for JVM, but I already added flags -d64 and -Xmx6g. At the highest point only 2gb of memory is reserved. I think here is another problem. What if GC only after 1.5k files starts clearing the garbage?
Also I build each file separately, maybe here is a way to build everything at once and get a lot of CompilationUnits?

Thanks
