Hi there - I've tried cloning https://github.com/Kotlin/kotlin-koans and both via the command line or intellij I get the same error when trying to run gradle test:

e: java.lang.ArrayIndexOutOfBoundsException: 446
        at org.jetbrains.org.objectweb.asm.ClassReader.readUnsignedShort(ClassReader.java:2464)
# ... (too long for Slack)

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileKotlin'.
> Internal compiler error. See log for more details

Any suggestions?
