Too many startServer() and clientDestroyed() got invoked when spring created and java code created client/server mixed used.

From the testcase, there are 2 servers(one is spring created,the other is code created) and 2 clients(one is sprint created,the other is code created), when install/uninstall this bundle to osgi container, startServer() got invoked 3 times and clientDestroyed() got invoked 4 times!
