adding a new line to code and applying change results in debug stop (and starts debug of another project file)

steps to reproduce
-open project stored in 
http://qa.netbeans.org/modules/debugger/promo-h/MemoryView.zip
-Toggle line breakpoint on line 25 of the file FixAndContinue.java 
-Invoke Debug File action form context menu of file FixAndContinue.java in Projects view 
-Invoke Step Into until debugger stops on line 26 
-Insert line before line 30 with code System.out.println("Added line"); 
-Change method call on line 31 to afterFix(); 
-Invoke Apply Code Changes 
-Invoke Step Into until end of application
when reaching line 30 an error message is thrown:
#
# An unexpected error has been detected by Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x061c372a, pid=7714, tid=3084200848

debug of FixAndConstinue ends and starts debug of MemoryView.java

This behaviour was not observed in another file, with which I tried to reconstruct this bahaviour. I will post it here.

Although it may not be isssue for debugger(or even for netbeans), I post it here, since program normally does work and 
I think it really might have something to do with debugger.
