Can not relocate class: JDK8 compatibility

[supercarl87]

Hi ,

I tried to relocate a class using this plugin. I got the error below. Does this plugin work with JDK 8?
I am using
com.github.jengelman.gradle.plugins:shadow:1.1.1
Gradle 2.0
JDK 8

ex

I suspect that a newer version of ASM is required for JDK8 compatibility.
