Description Jiri Skrivanek 2014-09-03 10:07:02 UTC 
If you run garbage collection from NetBeans profiler it increases heap dump. It is reproducible with JDK7 and JDK8, not with JDK6. To reproduce:

- create sample Anagram project
- right-click project node and choose Profile
- select Telemetry and click Profile
- when profiling starts heap dump is for me 120 MB
- click GC button and it decreases to 75 MB
- click GC button again repeatedly and heap size increases to 1,5 GB
