Crash on OpenJ9 JVM

See original GitHub issue

When Finagle is used with the OpenJ9 JVM, it crashes with a java.lang.UnsatisfiedLinkError.

Expected behavior

When running on a non-Hotspot JVM, I would expect JVM stats to be unavailable, but things should otherwise work normally.

Actual behavior

When starting a Finagle application on OpenJ9, I get this stack trace:

Exception thrown in main on startup

I believe that the offending code is in Jvm.scala:

  private lazy val _jvm =
    try new Hotspot
    catch {
      case NonFatal(_) => NilJvm
    }

Attempting to create a Hotspot results in a java.lang.UnsatisfiedLinkError which I believe is not NonFatal.

Steps to reproduce the behavior

Finagle and Twitter-util version 7.1.0
Build an application using Finagle
Build a docker image for that app using adoptopenjdk/openjdk8-openj9:jdk8u162-b12_openj9-0.8.0 as the base
Run the application inside the container

Java version inside the conatiner:

openjdk version "1.8.0_162"
OpenJDK Runtime Environment (build 1.8.0_162-b12)
Eclipse OpenJ9 VM (build openj9-0.8.0, JRE 1.8.0 Linux amd64-64 Compressed References 20180315_120 (JIT enabled, AOT enabled)
OpenJ9   - e24e8aa9
OMR      - 3e8296b4
JCL      - ee1e77df1d based on jdk8u162-b12)

Please list all relevant steps to reproduce the observed behavior.
