By repeatedly clicking the refresh button in IE I noticed a serious memory
leak. It appears in some cases (not all) doing so causes the plugin to
leak threads. The attached screen shot below shows the state of the plugin JVM
after leaving the applet page.
This is with 1.6 b99, Internet Explorer.
I'm filling against deployment for the initial evaluation, this may turn out to be a problem else where in the VM.
I've also attached a test case from Chris.
