Its not that it wasn't working, but one of the two device files is a real 
BLOCKING entropy gatherer and it does not report data if there is insufficient 
entropy to report.  It has a limited buffer (in the kernel) to maintian the 
last X bits of entropy.  Once you ehaust it by reading it all into your 
application it will block (unless you open the OS file desc non-blocking, then 
it will report kernel error EAGAIN but no data).

The other device is kernel random number generator that is fed from the kernel 
entropy gatherer, this will consistancy emit random data never blocking.

The only meaningful diag for a 'lockup' is a thread dump so that the state of 
the server can be identified.

Tell me how to get a thread dump from JBoss when it's locked up, and I'll post 
it.

Hmmm, maybe this is an issue with the use of /dev/random in the JDK on RH Linux 
???

That's it! changing:

The problem seemed to be that the security provider used /dev/random as an
entropy generator, and it somehow wasn't working. By editing the
$JAVA_HOME/jre/lib/security/java.security file and changing the property:

securerandom.source=file:/dev/random

to:

securerandom.source=file:/dev/urandom

did the trick!  now my crypto unit test finishes AND jboss starts up.
