Note: Not happening when using Scala 2.11.
So, this could be related to classycle and Java 8 bytecode.

java.io.UTFDataFormatException
UTFDataFormatException is described in the javadoc comments as:
Signals that a malformed string in modified UTF-8 format has been read in a data input stream or by any class that implements the data input interface. See the DataInput class description for the format in which modified UTF-8 strings are read and written.
author: Frank Yellin version: 1.13, 05/13/04 see: java.io.DataInput see: java.io.DataInputStream#readUTF(java.io.DataInput) see: java.io.IOException since: JDK1.0
