Loader constraint violation

[noorlander]

Hi!

I get this error and have now spent a day to figure out what causes
it. Anyone an idea?

Thanks in advance for your help.

Please do not multi-post.

I cross-posted to unify the thread, even though both groups have pretty much
the exact same readership. Multi-posted messages fragment threads, discourage
replies, and annoy those who try to help.

You should read the FAQ post and its links, entitled
"comp.lang.java.{help,programmer} - what they're for (mini-FAQ 2006-03-31)" by
David Alex Lamb. It explains how best to use these groups.
