Error occurred during initialization of VM Could not reserve enough space for object heap

ERROR: Error occurred during initialization of VM Could not reserve enough space for object heap

Characteristics: Could be another version of Java or Eclipse

Situation: Using ANT as a compiler, JDK 1.7.0_51, Struts, Eclipse Kepler, Windows 7, Jboss EAP 6.1

Possible solution: Change the JDK. In this case I had JDK 1.6.0_21. Moving to Java7. Its a MUST than the JDK and Eclipse must be for 32 bits both. (or 64, but better 32).
