quasar-core agent fails to run on JDK9+160

[chrisr3]

I have a project that is compiled for JDK8, but that I am trying to run on JDK9. However, the quasar-core agent is failing to instrument:

[quasar] ERROR: while transforming jdk/internal/vm/PostVMInitHook: null
java.lang.IllegalArgumentException

I am suspecting that this is because the latest JDK9 snapshots have removed some internal APIs that Quasar is using, e.g. according to jdeps -jdkinternals quasar-core-0.7.8-SNAPSHOT-jdk8.jar:

JDK Internal API                         Suggested Replacement
----------------                         ---------------------
sun.misc.Resource                        Removed. See http://openjdk.java.net/jeps/260
sun.misc.URLClassPath                    Removed. See http://openjdk.java.net/jeps/260
sun.misc.Unsafe                          See http://openjdk.java.net/jeps/260

AFAIK JDK9 is not really supported at this stage. @pron Is that correct and do you know of any news about that?

Is this issue solved? I am facing a similar issue while running on open jdk 11

Does this not work with java 9, I head over here after seeing this.

upgrade asm version to 9.x
