runnning with Mustang

September 14, 2005

Class verification errors were the order of the day when I first started using Java 5. With java six it's something else:

Error: Can't read [/usr/java/jdk1.6.0/jre/lib/rt.jar] (Can't process class file [com/sun/accessibility/internal/resources/accessibility.class] (Unsupported version number [50.0] for class file format))

The last time some of the problems were tracked down to an incompatibility with the installed version of proguard which had in fact been already fixed by the time I first tested obfuscation with java 5 but not so this time, it doesn't really matter because an applet/application that makes use of the java 6 features is still a long way down the road. Precious few make use of java 5 specific features even today.

I did find the browser dying on me when loading some applets. I am yet to determine the cause.
