RFR 8038321: RMIConnector_NPETest.java can't start rmid if running on fastdebug or Solaris-sparc

[shanliang]

Hi,

The test is to test a NPE during creating a JMX RMI server, but it got 
timeout when starting a RMID, the fix is to remove this timeout, it is 
not easy to have a reasonable timeout working for different testing 
machines, and the test is not implemented to test sun.rmi.server.Activation.
