Large memory use by class CustomClassloaderJavaFileManager

[ghost]

There appears to be a consistent, large memory use by the class CustomClassloaderJavaFileManager (16% of bytes arrays accoording to heapdump), coming from the class com.dexels.navajo.compiler.tsl.custom.CustomJavaFileObject. The cause appears to be a "double" allocation of both a byte array together with a file in tmpDir, where the byte array appears to not be used anymore.

Further investigation of (memory) performance improvement here might be useful.
