Description Vladimir Lahoda CLA 2003-06-17 11:05:00 EDT 
The attached class Testik.java throws exception java.lang.VerifyError: (class: 
com/amaio/Testik, method: test signature: ()V) Illegal target of jump or 
branch. when compiled by JDT incremental compiler.
The same class compiled by standard JDK 1.4 compiler works fine.
I enclose the javap disassembly file (disassembled.eclipse), the problem is 
apparently caused by the line "25 goto 38" which attempts to jum to non-
existing label 38.

(The awkward sourcecode in Testik.java was originally generated by javacc...)

Which Eclipse build are you using ?
Comment 7 Philipe Mulet CLA 2003-06-17 13:17:40 EDT 
Suspect this to be a dup of bug 37040
Comment 8 Philipe Mulet CLA 2003-06-17 13:18:52 EDT 
We may consider backporting this fix for 2.1 maintenance stream as well.
Comment 9 Philipe Mulet CLA 2003-06-17 13:21:17 EDT 
Actually, I was wrong. This is a dup of bug 37621 which already backported to 
2.1.1.
