Description Olivier Thomann CLA 2002-10-22 09:46:47 EDT 
Using 1118, I got a ClassFormatError when I tried to run a class that contained
a compile error.
java.lang.ClassFormatError: org/eclipse/jdt/internal/compiler/parser/Scanner
(Invalid start_pc/length in local var table)

	at ScannerTest.main(ScannerTest.java:12)
Exception in thread "main" 

This class is the Scanner class having a local variable used. The bug is not in
the problem method, but in two other methods. I will investigate in self hosting.
Comment 1 Olivier Thomann CLA 2002-10-22 11:51:51 EDT 
The problem was due to a resize in the byte array and the fact that in some
cases I don't store a 0 in the array. Instead I was offset the index by 2.
Fixed and released in 2.1 stream.

Verified.
