Title: fixed wrong annotation name

Using the @Index-Annotation led to a ClassCastException:
java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Boolean
at org.datanucleus.api.jpa.annotations.IndexHandler.processMemberAnnotation(IndexHandler.java:38)

This should fix it, but its untested.
