Is it advisable to have the following JVM option set in Tomcat 7 (with

-XX:+DisableExplicitGC
Or will this prevent Tomcat itself from calling System.gc() when it
needs to?
Tomcat is probably not doing that anyway (I'll let someone else answer that part), but
there might be some monitoring/control application running, which could be using that.
The reason I am thinking of this, is that I have a couple of installations where because
of an unruly webapp leaving tons of connections open in CLOSE_WAIT state, I am using a
jmxsh script regularly, to provoke such GC's to clean them up.
If I set the option above, that script would probably fail, and the system would slowly
get to an inoperative state.
