Hello, Currently the jdk8u codebase fails some JTreg Hotspot tests when running in the -agentvm mode. This is because the ProcessTools class is not passing the classpath. There are substantial time savings to be gained using -agentvm over -othervm.
Fortunately, there was a fix for jdk9 (8077608) that has not been backported to jdk8u. The details are as follows:
http://mail.openjdk.java.net/pipermail/hotspot-dev/2015-April/017937.html https://bugs.openjdk.java.net/browse/JDK-8077608 http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/af2a1e9f08f3
The patch just needed a slight change, to remove the change to the file "test/compiler/uncommontrap/TestUnstableIfTrap.java" as that test doesn't exist on jdk8u.
My colleague Ningsheng has kindly hosted the change here:
