[news.eclipse.technology.memory-analyzer] Re: Analyser 'loosing' over half of the used memory

You have two possibilities (described in a little more detail on the FAQ page): Either look at the histogram of unreachable objects or (during the initial parsing) let MAT mark those objects as pseudo GC roots and therefore prevent their removal.

http://wiki.eclipse.org/MemoryAnalyzer/FAQ#How_to_analyse_unreachable_objects

I ran the parser with keep_unreachable_objects and the reported heap size rose to 2.8Gb, still nowhere near what it actually was at the time the heap was taken.
