In the following example, bytecode index 37 in the method void test()
" 37 goto 43"
is mapped to line number 47, which is not correct.

Example, java code:
***************************************************************************************************
/*
Testcase: Debugger steps into forbidden code
http://www.netbeans.org/issues/show_bug.cgi?id=33921

  Product Version = NetBeans IDE 3.5 RC2 (Build 200305182350)
  IDE Versioning = IDE/1 spec=3.42.1 impl=200305182350
  Operating System = Windows 98 version 4.10 running on x86
  Java; VM; Vendor = 1.4.1; Java HotSpot(TM) Client VM 1.4.1-b21; Sun Microsystems Inc.

How to reproduce:

- Set a breakpoint on first line in test()
- Single-step [F8] through test()

Expected behavior:
- The debugger should skip the line "deleteAllSystemFiles();"

Actual behavior:
- The debugger steps onto the line "deleteAllSystemFiles();"
