intermittent DeadListenerTest.java failure

The SDK/JDK test failed during a Serviceability stack test run
on Solaris X86:

    javax/management/remote/mandatory/notif/DeadListenerTest.java

The failure only happened on one config out of eight so it looks
like the failure is intermittent. Here is the failing config:

    $ cat sdk-mm_jmx-prod-server_bh_hsx_rt_exp_fds_dcubed-fast-comp.solaris-i586/do_sdk_common_tests.16778.version
java version "1.8.0-ea"
Java(TM) SE Runtime Environment (build 1.8.0-ea-b39)
Java HotSpot(TM) Server VM (build 24.0-b10-bh_hsx_rt_exp_fds_dcubed-product-fastdebug, compiled mode)


Here is a snippet from the failing .jtr file:

I'm going to guess that the use of fastdebug Server VM bits with
the -Xcomp option made the test take longer than expected.
