Here it is:
java version "1.5.0_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_02-b09)
Java HotSpot(TM) Server VM (build 1.5.0_02-b09, mixed mode)

Right, that looks strange. BTW, I actually had one more strange effect
noticed on Windows when I was sending a lot of events to eventserv (also
C++) and then shutdown all consumers and later all suppliers. After some
time (already without any load on it) eventserv took all CPU resources and
then crashed. The situation repeated twice. Unfortunately I can't report
this as bug because after that I switched to Solaris and have not enough
details about the situation - probably I compiled it incorrectly. Also that
crash appeared in Windows+Cygwin environment and was not repeatable under
pure Windows conditions. But in principle I think that is possible that
recompiling event producers and consumers using different JDK may affect
eventserv functionality. 
Please do not assume that example as a bug report because the problem I
experienced was in the environment not supported by IONA and I'm not ready
to provide more details.

Here it is:
