I20110830-1241 Cocoa 32bit on 10.7

When I open a Java editor, do Navigate > Show in Breadcrumb, and then click an arrow in the breadcrumb, I see a gray palette window with a mini-titlebar flashing up before the breadcrumb dropdown opens.

This is a strange bug that I can consistently reproduce in various builds (including e.g. 3.7.1RC3 M20110831-1030-macosx-cocoa-x86_64) as long as I'm in the host workbench. But I've never seen it in a runtime Eclipse instance.


To hunt it down, I started a second eclipse workbench from the Terminal like this:

./eclipse -vmargs -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005

In my dev workspace, I created a Remote Java Application debug configuration with port 5005. After I've prepared everything in the second workbench, I set a breakpoint in org.eclipse.jface.viewers.AbstractTreeViewer#inputChanged(...) on line 1526 at "tree.setRedraw(true);".

The palette window flashes up inside that call when I step over it. Precisely, it's inside "window.orderBack(null);" here:

The palette window also flashes up when I select a Java identifier in the editor and then press F2.

This is the same as bug#369599. I could not reproduce bug#369599 while self hosting either. I do not know what is the difference.

The problem does not happen with N20120131-2000.
