I get the following assertion crash each time I exit from VisualTool:

We must use lockFocusIfCanDraw instead of lockFocus on NSView objects on Mac to avoid locking focus on hidden views.

If you run HelloWorld and close the window you will see the failure. Note that something has changed in glass recently to trigger this assertion in more cases. This is now a serious regression from 2.0 that affects all programs on exit. For 2.0.2 we either need to fix the underlying cause or suppress the assertion message. Note that it appears to have been caused (or more likely, exposed) by the following changeset: changeset: 582:eac06eab37ad user: Anthony Petrov date: Fri Oct 07 19:31:08 2011 +0400 summary: Follow-up fix for RT-17213: com.sun.glass.ui.mac.MacView are not garbage collected

This is probably workarounded by RT-15601 and needs to be looked at when fixing RT-14271.

[View lockFocus] fails, which makes the later code throw an assertion. Looks like we're trying to draw into a view, which itself is already hidden or detached from the Window or Window is hidden - basically need to make sure the order of hiding/closing window, detaching View is correct.
