The web application I develop creates many threads in a "StartupServlet"'s init method and destroys them in the destroy method.
The threads work in an infinite loop unless they are signaled to stop. They have to create a lot of list objects, that is, they produce a lot of garbage object (objects left for the GC).
The reason, I create them within a servlet environment is because they need to invoke remote ejbs. I pass them an InitialContext object prepared within the servlet environment. (and invoking remote EJBs in a standalone application can be quite cumbersome.)
The threads are marked as daemon threads, so that they don't hinder the WAS process (main process) from shutting down.
My questions are :
1) Websphere runs on the IBM JVM. What are the odds that the IBM JVM's GC doesn't collect garbage objects created by my custom threads ?
2) Are there any other drawbacks in creating custom threads within a servlet environment ?

Just FYI, you might want to look at Asynchronous beans at http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/topic/com.ibm.websphere.nd.doc/info/ae/asyncbns/concepts/casb_asbover.html as a way of running multiple threads within WebSphere Application Server.
