[7u80] Request for approval for CR 7142035 - assert in j.l.instrument agents during shutdown when daemon thread is running

[Andreas Eriksson]

Hi,

Requesting approval for a backport of JDK-7142035 from JDK8 to 7u80.
If you use a java.lang.instrument agent trying to instrument a java 
application with a daemon thread, you could trigger an assert inside the 
JPLIS code.
The changeset imported cleanly from jdk8.
