Ivan,

Heh. I think we might have been looking at the same problem at the
same time. I was actually thinking of a more general solution by
restoring the setContextClassLoader() call in GBeanInstance.java at
line 912. What do you think?

Using TCCL is really a pretty dreadful non-modular hack.  I'd prefer to avoid supplying temptation to use it to all gbeans and only supply it where it's really essential.

If you decide to put it in anyway, I think there's another commented out line 1117 to consider.

thanks

I am fine with adding it in the gbeaninstance class, it might slove most of
the problems.
Usually, I add the set action in the first line of the try block, so that it
should make sure that finally block would always be executed. ^_^
