Java Update and ProGuard obfuscator/optimizer Christian Roth Mon Jun 22 04:00:52 2009 

Hello,

this is just a heads-up to anyone using ProGuard <http://
proguard.sourceforge.net/> to obfuscate and optimize their Java code:
After installing the latest Java Update 4, my jars created by ProGuard
seem to be broken.

I was using ProGuard 3.4 for a long time and never had any issues with
our application. After installing the latest Java update, the jar
produced by ProGuard started to throw an ArrayIndexOutOfBounds exception
(when the unprocessed one does not).

I do not know if this is a problem with ProGuard or the Java update at
this time. I just want to make sure you do a thorough test of your
ProGuard generated jars built after the Java update to make sure they
still work, even when you did not change anything else in your configuration.

My workaround for now was to (1) update to ProGuard 4.4beta (4.3 was not
enough) and (2) disable any optimization routines (running them produces
an error in ProGuard itself) by specifying -dontoptimize in the ProGuard
configuration.


-Christian
