can u post the complete error message?
Also please check if u are in the %JBOSS%/bin directory before running the run.bat or run.sh
Unable to initialize threads: cannot find class java/lang/Thread
Press any key to continue . . .
Notice I am in the bin directory
Looks like I had another jdk environment screwing everything up. I moved that jdk path (created by an oracle cleint) behind the proper (sun) jdk path in my environment settings and jBoss started right up.
Thanks for your help

I've been bitten several times by this.
