Re: [jibx-users] IllegalAccessException when running on JRE 6.0

[Dennis S. <dm...@so...>]

I'd appreciate it if anyone else encountering problems with Java 6 can 
post information. I'm still using Java 5 or earlier for all my work, so 
I'm not going to see the problems myself. I'll still look into any 
issues people find with Java 6, though.
