Build: NetBeans IDE 8.0 (Build 201403101706) VM: Java HotSpot(TM) 64-Bit Server VM, 24.45-b08, Java(TM) SE Runtime Environment, 1.7.0_45-b18 OS: Windows 7 User Comments: GUEST: during netbeans close GUEST: Had about 20 files open. most of them java, 2 or 3 of them xml. one xml file is big - just over 1MB. i selected it and hit SVN Diff. it showed me the difference. I hit svn update. It froze for several minutes. I checked the JVM memory - perm, old, and eden were completely full. there was a lot of GC activity. Number of OLD Gen total collections (in a space of 5 to 10 minutes) shot up from 130 to 230 total collections. I eventaully clicked the X button to close netbeans. I only have a few standard java files open. It shouldnt eat up 1.5GB of the allocated JVM memory and not be able to garbage collect. It looks like its buiding up too much memory usage while editing/diffing the 1Mb xml file ShivarajRH: When editor idol. Memory usage is too high. And exceed the memory limit. GUEST: ???????????? GUEST: Editor's becomes slow during normal code edit, and eventually crashed.
