Description Libor Kotouc 2005-05-17 12:44:39 UTC 
When user modifies a source file, then debugger maps OLD CLASS lines announced
by debuggee process to the NEW SOURCE lines in that source file.

This mechanism does not cover the situation when that source file is recompiled
and the resulting class file is reloaded by JVM. Debugger then incorrectly maps
the NEW CLASS lines to the NEW SOURCE ones because it does not know about class
file reloading.

Maybe, there should be some kind of the line map reseting when a class file is
reloaded.

It also depends on whether you're stepping inside the obsolete (old) method
(there remains the old code in methods that are on the current stack) or the new
method (when you enter the method after class reload).

The obsolete and reloaded methods needs to be handled differently.
