Regardless of the local version of java the user is deploying/building Kaleo-Forms, this error is generated. This is because the library jar files were built using Java 7. The fix will be to regenerate these files with Java 6.

Reproduced
Plugins 61x: yes 54541006a60ba31eab50f00ab99b815ed1392010
Plugins 62x: no, 62x uses Java 7, so the generated jars are fine.
70x/master: no, the kaleo-forms plugin no longer exists.
