Steps:
1. When suspended on a breakpoint turn on Thread Groups
2. The tree will be updated showing the groups now
3. Set selection back on the breakpoint from 1.
4. Turn off Thread Groups
=> Nothing happens

I can't reproduce. Is there anything in your .log?

You're right, it doesn't happen every time. Here are more detailed steps:
1. Check out o.e.compare
2. Set a break point at line 96 of org.eclipse.compare.structuremergeviewer.StructureCreator, it's in StructureCreator.createStructure(Object, IProgressMonitor) where internalCreateStructure is called
3. Start runtime Eclipse in debug mode
4. Compare two Java files
5. When the breakpoint is hit, turn on Thread Groups via Debug view's drop down menu
6. The tree will be updated, selection lost, so set selection back on the breakpoint from 2.
7. Turn off Thread Groups
=> It's not that nothing happens as I stated in comment 0... stack trace gets duplicated, take a look at the following screenshot

I noticed this again in: 

Version: 3.8.0
Build id: I20111101-0800

I think the underlying problem is that we are not properly handling the backing data items as mentioned in bug 126379.
