Will comment out until fixed.

Fixed.

Still failing.

I tried to fix
options.keymap/test/unit/src/org/netbeans/modules/options/keymap/KeymapViewModelTest.java#testChangeShortcutsOk. But it
is still failing. Maxi, could you look at it? I don't exactly know what it is supposed to do. model.apply() should store
changed shortcuts but it calls "model = new KeymapModel ();" which resets it. I am lost here. Remember that it fails
only in debugger (toggle breakpoint at line with checkShortcuts) because model.apply() is posted to RequestProcessor.

Log: #137748 - testChangeShortcutsOk still failing.

The "model = new KeymapModel ();" does not break anything, since call to changeKeymap stores everything to looked-up keymapmanagers. Jirko, is it a 
problem that it fails in debugger in described scenerio? Normally, the test passes OK for me. In case not, I suggest to close this issue and leave the test 
as such:

public void testChangeShortcutsOk () {
        KeymapViewModel model = new KeymapViewModel ();
        Map<Set<String>,ShortcutAction> shortcuts = setRandomShortcuts (model);
        System.out.println ("apply changes");
        model.apply ();
        System.gc ();
        model.apply ();
        System.gc ();
        checkShortcuts (model, shortcuts, true);
    }

The problem is that the test failed randomly and if you run it in debugger it fails regularly. As I said it is because
model.apply() is done in RequestProcessor and in fact it doesn't executed if you just run it. The test itself finishes
before RequestProcessor processes its tasks. To reproduce reliably add something like this to the test:

        model.apply ();
        while(model.isChanged()) {
            Thread.sleep(100);
        }

Then the test fails everytime.

This needs to be redesigned, I agree. apply() w/o RequestProcessor would take ages, so we have to find another way of applying the changes.
