Long shot on a IllegalAccessError

[Pete Helgren <Pete@xxxxxxxxxx>]

I am in the final stages of working on my presentation for Common (on 
Monday at noon BTW) and I have run into an issue with BIRT that I can't 
solve.  When I invoke a Birt Report from a standalone application (not a 
web app) I receive the following exception:

Exception in thread "main" java.lang.IllegalAccessError:

I have a wrapper class, BirtGenerator.java that has a few convenience 
methods.  This wrapper is then wrapped by some RPG procedures to make 
this available to ILE RPG programs.  It doesn't make any difference 
*how* the wrapper is invoked, either by calling the method on the class 
directly in QSH (as above) or calling an RPG program that invokes the 
wrapper, in both cases I get the same exception.  I do NOT get the 
exception if I invoke the same class when I test within my Windows 
development environment.

I tried using both the 32bit Java 5 and 32bit Java 6 JVM on the i (IBM i 
6.1) and I get the same message.  I am current on PTF's for Java.  This 
might be a JIT related thing but I can't figure out how to disable JIT 
for the JVM so I can't tell for sure.

I DID see this once, even in my Windows environment, but it seemed to 
stem from a mismatch in Birt versions.  I have checked and rechecked the 
jars and both environments seem to match.  Unless the jars are cached 
somewhere on the i, I don't think a version mismatch is the issue.

I could use *any* ideas you might have.  I don't quite understand what 
is being accessed illegally here.  Not much in the Birt method 
ExtensionManager.initialize() to go on.

Help!
