I believe I'm seeing a memory leak as a result of a Manager
deploy/undeploy. I have a very simple test case: a Servlet that has a
static field that refers to an object (Foo) that allocates a large chunk
of memory. I've instrumented both the Servlet (init(), destroy(), and
finalize()) and Foo (ctor and finalize()). The Servlet has been
configured to load on startup.
On a deploy, I see:
Foo.ctor (during class initialization of the Servlet)
Servlet.init():
On an undeploy, I see:
Servlet.destroy()
Servlet.finalize()
I never see Foo.finalize(). If I continue to deploy/undeploy
repeatedly, eventually the VM reports an OutOfMemoryError when I try to
deploy. Running the VM with -verbose:gc and "encouraging" GC whenever
possible, I see that after each undeploy, memory usage goes up roughly
by what I've allocated in Foo.
Any ideas?
