[Pellet-users] Cannot stop timer exception

Hello,
   I'm trying to run a construct query on a Jena/Pellet Mysql backed
model.  The query runs fine from top-braid composer's SPARQL window with
inferencing on, but when I try to run it from my java/jena app, I get
the following exception.  I don't know where to begin to look for the
problem, any ideas?  I do run other queries on this model fine from my
app, it's just one particular query that is causing problems, and again,
it runs fine from top braid composer.

java.lang.UnsupportedOperationException: Cannot stop timer 'rule-choose'
