Yes, I'm talking about the same problem in the console attempting to
list all of connectors. I hadn't noticed the WARNING messages that you
are pointing out. I'll have to run it again and see if I get those as
well.
If those messages are correct then there is something wrong with the
classloader attempting to pull Jetty classes into the tomcat scenario
and vice-versa. It's strange that there are no jetty classes referenced
in the call-stack for the tomcat error. If we are always attempting to
load classes from the other container then I don't know why we don't get
the ERROR everytime instead of the WARNING.
Perhaps between us we can figure out what's going on here.

I guess TomcatWebSSLConnector is having problems. I have hit upon this

I suggest to remove the Tomcat HTTPS Connector from the Tomcat
configuration for now and build rest of the code.

Well I've figured out a way around this problem but I can't for the life
of me explain why it eliminates the problem. This may even be a
problem
in CGLib but this work around at least avoids it for now.
It seems to be a problem with the selection of the class loader.
Here's the class/interface configuration with the problem:
- We currently have defined 2 interfaces that both extend from a common
interface (say A and B that extend from Z). An implementation
class(IA) implements one of the interfaces(A). Another implementation
class(IB) extends IA and implements B.
- When we attempt to create a proxy for the GBean object, we get the
NoClassDefFoundError exception in the original post while attempting to
load the interface A.
I took a look at Jetty(which isn't hitting this problem) and the only
difference appeared to be another interface(C) that is in the same
package as B between the interface B and the class IB (which is really
strange because A was the interface pointed to by the error ... not B).
After rebuilding I no longer get the NoClassDefFoundError exception.
Anybody have an explanation or theory on this?
Does somebody with more experience on CGLib think it's likely a problem
there?

No, this interface reduction is doing it's job to ensure that we have
the least number of interfaces while still representing all of the
object's capabilities.
