Bug #214455 - NB erroneously attempts to create a FieldBreakpoint instead of a Line breakpoint on an anonymous inner class

http://netbeans.org/bugzilla/show_bug.cgi?id=214455

Description:
The logic, that decides which kind of breakpoint should be submitted at 
the selected line, iterates through the javac source tree to find the 
field declaration for field breakpoints. But it has iterated too much, 
it can get from the method of an inner class to the declared outer field.

Fix:
The fix is to stop the iteration process when we find a method tree.

Risk:
Localized to submission of field breakpoints

The fix has been reviewed by Jaroslav Havlin
