(Hashtable does not allow null values, which seems to
be the cause of this exception. HashMap could be used
instead.)
Probably there is either a null message property
(SpyMessage does not check for null String values) or
some sort of race condition as I haven't seen this
exception before...

I'll fix it -- I still seem to have CVS write access.

Nulls are allowed according to the spec (String and Object
properties)
Elias you have cvs write?
A HashMap for the temporary copy
sounds like correct the solution.
Can you fix it for 3.2.2 release, i.e. before the weekend?
If not, I'll do it. Don't forget jboss-head
Regards,
Adrian
