[8u40] RFR backport 8058715: stability issues when being launched as an embedded JVM via JNI

[david buck]

Hi!

This is a request for approval to backport this fix to jdk8. The jdk9 
change applies cleanly and I have already built and tested on 8.

BUGURL: https://bugs.openjdk.java.net/browse/JDK-8058715
JDK9 changeset: 
http://hg.openjdk.java.net/jdk9/hs-rt/hotspot/rev/6748f6322b92

Cheers,
