[jacorb-developer] Bad type on operand stack error when using JacORB and JBoss modules

[Rob Ratcliff]

Hi,

I am using a GUI framework that use JBoss modules to manage plugins. My
plugin has a dependency on JacORB. I'm using the classloader for my
plugin by setting
Thread.getCurrentThread().setContextClassLoader(this.getClass().getClassLoader());
and I set the tccl property in JacORB
(System.setProperty("jacorb.classloaderpolicy", "tccl");

Any ideas for resolving the Bad type on operand stack error in the stack
trace below? Is there any way to eliminate the dependency on the JDK's
CORBA classes?

Thanks,

Rob
