Please review the change that fixes an intermittent tests failure.
The tests javax/management/remote/mandatory/connection/ReconnectTest.java and
javax/management/remote/mandatory/connection/MultiThreadDeadLockTest.java use
specific settings for server timeout that in some cases (e.g. when the test is
run with -Xcomp)
result in JMX server connection timeout thread unexports the remote object
while the client
connection is still in the progress. Below is an example of a such stacktrace:

The fix adjusts the server timeout the tests use for "test.timeout.factor"
system property.
Testing: Mach5 tests are in the progress.
