Please anyone take a review:

By assigning to a local variable hopefully it stays alive on the stack
during the whole method.

*Chris*: I didn't indented the whole test by wrapping them into a
try-finally (or try-with-resources) block. The test runs in othervm and
I guess the sockets will be closed anyway.
Thanks

Hi All
I have a test that basically looks like:
int p = new ServerSocket(0).getLocalPort();
//....
new Socket("localhost", p);
Recently it's failing on solaris-i586, and after some investigation, I
realize that the ServerSocket object is GC'ed and auto-closed.
(But why only recently?)
So I change the first line to
ServerSocket ss = new ServerSocket(0);
int p = ss.getLocalPort();
and it's running fine.
I want to know if the ServerSocket object still has a chance to be
closed. If yes, I'll add a
ss.close();
at the end to be safer.
Thanks

HotSpot changes I assume, perhaps changes to the reference processing or
default heap settings.
Right, I assume there was some VM change that started this test to fail
recently, but clearly this is a test issue. It was just passing all this
time by accident, and there is an inherent race between the test and the
GC/finalizer thread.
You should fix the test as you suggested. Also close the serversocket in
a finally block ( or equivalent ). You should not rely on the finalizer
to close it out.
