Hi everyone.

I've been using Geronimo 1.0, and now 1.1, as the app server for the
development of a JCA connector for our proprietary EIS and generally
been very happy with it.

I've had no problem running servlets, deploying WARs, and the like.
However, I've run into a problem deploying a RAR that I built.  I view
it as highly probably that there's a bug somewhere in my resource
adapter, but it seems to be triggering a bug in Geronimo, which appears
in both Java 1.4.2 and 1.5:

23:52:38,091 ERROR [GBeanInstanceState] Error while starting; GBean is now in the FAILED state: abstractName="com.celebrityresorts/rcc/0/rar?J2EEApplication=null,JCAConnectionFactory=Celebrity%20Resorts%20RCC%20development%20instance,JCAResource=com.celebrityresorts/rcc/0/rar,ResourceAdapter=com.celebrityresorts/rcc/0/rar,ResourceAdapterModule=com.celebrityresorts/rcc/0/rar,j2eeType=JCAManagedConnectionFactory,name=Celebrity%20Resorts%20RCC%20development%20instance"

        at org.apache.geronimo.gbean.runtime.GBeanInstance.startRecursive(GBeanInstance.java:540)

and so on.  The only thing I can figure is that somehow the Exception
getting thrown is null, but I can't see how, as it seems to stem from

   throw new Exception("A reference has failed so construction can not complete");

so I'm very confused.  Of course it's also quite late for me and I may
be reading the stack trace wrong.

Any hints?

Thanks,
Tim
