GWT compiler fails with Bad class version

Solution: This might happen because of incorrect version of Javac used by the GWTcompiler or the incorrect version of the jar files in project space.

We observed ant in netbeans is using the default JVM of the netbeans ide instead of JVM set for the project. Please change the default JDK used by neatbeans by changing netbeans.conf file.
