RFR(s): 8066835: TEST_BUG: javax/management/remote/mandatory/connection/RMIConnector_NPETest.java fails

[Stuart Marks]

I broke RMIConnector_NPETest again. This time it was passing a timeout value 
that caused some time calculations to overflow, causing the RMI test library to 
time out prematurely.

Please review this fix, which is to limit timeout values to something reasonable 
and to change the test to use the default timeout instead of specifying 
Long.MAX_VALUE.
