Hello,
I'm doing my first steps with JBoss Cache at the moment (in stand-alone-mode)
and I have the following problem when I try to run some simple Unit-Tests:
I create a single TreeCache object in JUnit's setUp()-method and stop the
service with a stopService()-call in tieDown().
When I run only one test of the test-suite everything works fine. But when I
try to execute the whole test-suite the first test works and the whole rest
fails and a InstanceAlreadyExistsException is thrown (stack-trace is listed
below).
It seems that there is a problem with the registration/de-registration of the
MBean-server. When the second test is executed and the MBean tries to register
the 'old one' is obviously still registered. How can this happen?
Did I forget something?
Thanks in advance
Michael
