Description Greg Wilkins CLA 2011-06-21 23:58:08 EDT 
Ortwin Glück to jetty-dev
	
Hi,

I have found that:

WebAppContext app = new WebAppContext();
app.setContextPath(context);
app.setWar(warFile);
app.setClassLoader(new MyWebAppClassLoader(cl, app));
jetty.getHandler().addHandler(app);

app.stop();
jetty.getHandler().removeHandler(app);
app.destroy();

doesn't allow the webapp to be GCed if JMX is enabled.

The reason is that the MBeanContainer still has Container.Relationship
objects to the ServletHolders.

fixed in r3411

MBeanContainer now uses entirely weak references.

Michael can you double check this one and see that redeploying a webapplication does allow the servlets to be collected.

I think Target Milestone should be 7.4.3.
