Description

context

• running Swing GUI application in debugger
• Opened a new window on the current panel's java file
• I am pretty sure the debugger was stopped on a break point at the time.

expected

• Dragged the clone window out of the main window so that I can view it side-by-side
• Open a new Frame with the source file in it
• 2 x views on the same file

actual

• Thumbnail floated to the new position on screen
• Then nothing
• Thumbnail just stuck there
• Application window also locked-up (freeze)
• No response from Netbeans, ALT/F4 (Windows) didn't close window
• Needed to close Netbeans with TaskManager

Impact

• Lost work due to crash/shutdown
• Must repeat the debugging steps, it was a non-trivial exercise
