Thanks for your message. I believe this is related to the JRE version. What JVM are you building for?

If you are building based on the readme, I just noticed that it is in error. Java 6 may no longer be supported because it has hit EOL. I would recommend using Java 8, which is LTS and is still being maintained.

@lee-zhg We officially dropped support for Java 6 and Java 7 in 2.11.1.
