The memory is consumed by Java parsers.
Here are the top retained sizes:
com.sun.tools.javac.tree.JCTree$JCCompilationUnit	339,035,331 (30.3%)
java.util.HashMap					323,386,265 (28.9%)
org.netbeans.lib.nbjavac.services.NBParserFactory$NBJavacParser$EndPosTableImpl
							319,953,335 (28.6%)
There are 3,561 instances of parser and associated classes.

Comment 3 Svata Dedic 2013-09-13 09:05:50 UTC

The number of NbJavacParsers could correspond to the number of source files, IMHO. The indexing system contains some counter-measures against running OOM, but it seems the huge compilation task was requested by debugger, so it runs without those safeguards.
