RFR: 8285507: revert fix for JDK-8282704 now that JDK-8282952 is fixed

[Daniel D.Daugherty]

Revert (most of) the fix for JDK-8282704 now that JDK-8282952 is fixed.

This fix has been tested with Mach5 Tier[1-7] (about to start a Tier8) and I also ran
my StressWrapper_StopAtExit.java test using {release, fastdebug, and slowdebug}
bits for 12 hours per config. No failures for StressWrapper_StopAtExit.java.
