[dev from CVS, 040818] Every repaint, mouse move over listbox with fields and method names or selection change in this listbox causes storm of calls to MDR. It makes the dialog unusable even on fast machine. 1. Apply patch for showing call stacks in ExclusiveMutex (Issue 47456) 2. Rebuild 3. Open some project and java file (can be just basic J2SE project and Main.java) 4. Invoke Tools->Auto Comment 5. Click or do mouse move over listbox with methods/fields 6. You'll get a lot of calls to ExclusiveMutex from AutoCommentListCellRenderer for each paint Similar storm happens everytime when the IDE needs to repaint the listbox.

AutoCommentListCellRenderer is the culprit. I am working on this within javadoc module migration from srcmodel to jmi.
fixed as a part of issue #46262 /cvs/javadoc/src/org/netbeans/modules/javadoc/comments/ElementDescriptor.java initial revision: 1.1 /cvs/javadoc/src/org/netbeans/modules/javadoc/comments/AutoCommentListCellRenderer.java new revision: 1.21; previous revision: 1.20
verified in nbdev 200507131800. (about one mdr per click on listbox item, no mdr call when hovering with mouse over it).
