Description Rick Moseley 2007-07-31 19:18:38 UTC 
Startup the debug window on a piece of source code with variables in it.  Hover
the mouse over a variable that is out-of-scope(cursor does not turn into a
"hand") and then right-click.  The following backtrace occurs:

java.lang.NullPointerException

Log message:
	2007-08-01  Mike Cvet  <mcvet@redhat.com>
	
	* SourceBuffer.java (getVariable): Fixed assumption that variable 
returned
	from DebugInfo will never be null. Fixes #4871.
