JMH perfasm doesn't detect PrintAssembly output

[Claes Redestad]

Hi,

did you forget to add an appropriate disassembler plugin to your new
java install?

https://wiki.openjdk.java.net/display/HotSpot/PrintAssembly [1]

-XX:+PrintAssembly will appear to be working without it, but will not
be outputting assembly in a format that JMH can use.

Hope this helps!

[1] The binaries linked to from there should work for both OpenJDK and
Oracle JDK builds.
