No, "I was worried", not "I found a bug".

Ah, OK, then. The OInterceptor looked like it was rebroadcasting the
event to "sub-listeners". I understand you say that the Connection
class was listening at the same level as the OInterceptor, and was not
such a "sublistener". Then that's alright. Thanks for checking.

And I presume the HSQLDB driver was not such a listener, OK. The list
of listeners were taken from m_pStatCL, and I didn't see this list of
listeners being removed, so it seemed weird to me.

Thanks for reassuring me.
