GNUgcj problem?

Is this article?  I'm on Fedora Core 8 with yum installed java-1.5.0, 
and had exactly the same error as the author mentions. If so, anyone 
have any suggestions about what yum package I should use.

"Currently Nutch works only with certified JVM implementations, such 
as  Sun or IBM or BEA. GCJ is not supported."

I had problems with GCJ jvm also ( I am on CentOS ). It all went away
after I switched to Sun JVM.
