Adrian Brock closed JBAS-1492:
------------------------------
Resolution: Done
Fix Version: JBossAS-4.0.2RC1
Fixed. It will now use the System classloader if
getClass().getClassLoader() returns null, indicating that is where it was loaded
from.
> NPE: isInstanceOf on Class loaded by bootstrap classloader

>
> I called JMXConnectorServerFactory.newJMXConnectorServer to instantiate a
> RMIConnectorServer and registered it in the jboss mbean server. (Inside the
> Jboss AS 4.0.1).
> The resulting class javax.management.remote.rmi.RMIConnectorServer does not
> return a classloader in the call RMIConnectorServer.class.getClassLoader(),
> which is legal according to the jdk api documentation (see
> java.lang.Class#getClassLoader).
> Unfortunatelly the isInstanceOf method of org.jboss.mx.server.MBeanServerImpl
> does not take this into account. Thus I get a NullPointerException if I call
> isInstanceOf on that particular MBean.
