RE: Stange Exception

["Mike S" <security.vip@softhome.net>]

This is the JVM that I'm using:
java version "1.3.1_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_04-b02)
Java HotSpot(TM) Client VM (build 1.3.1_04-b02, mixed mode)

I did not test it on other VM's

This happens when I run the classes produced by Soot (1.2.3)
Except for the Library classes (java.*, javax.*, sun.*)

The modifications involve moving methods around, constructing
new classes from methods of loaded classes, introducing new
fields and a few statements into method bodies.

Mike.

Looks like something strange going on in the JVM. Can you provide more
details? What JVM are you using? Does it happen with other JVMs? Does
this happen when you run Soot, or when you run classes output by Soot?
What "simple modifications" are you making? Can you provide a minimal
test input that reproducibly causes the error?
