"IllegalArgumentException: size < 0" on ep-006

I'm getting "Wrapped java.lang.IllegalArgumentException: size < 0" on Android with the monkeypatch function. Any thoughts on what might cause this?

Thanks,

I'm getting a similar error: [ERROR] Wrapped java.lang.ClassCastException: org.mozilla.javascript.Undefined (file:///android_asset/Resources/app.js#3)

Any ideas?
