From Javadocs :-
Thrown when the Java Virtual Machine attempts to read a class file and determines that the major and minor version numbers in the file are not supported.
Try using a Java version which is supported by Maven.

Quoting the System Requirements from Maven home page:
Maven 3.3 requires JDK 1.7 or above to execute
1.6.0 (IBM or not) will not do.
