Hi,
yes, this is my configuration:
Win XP SP3,
Helios Service Release 2,
JBoss Tools Version: 3.2.0,
I linked my jboss not to the eclipse-build-in-jre, but to another local jdk (jdk 1.6.0_21)
I found a trick to stop it immediately without waiting anymore:
I go to the eclipse server-menu click ->Show In->Debug Mode->Terminate/Disconnect All.
