Which Java runtime are you using? OpenJDK by chance?
BTW, you're using mismatched Gemfire and Hibernate modules. If you're set on using GemFire 7.0 you should be using the Modules bundled with that distribution (although you'll probably still get the same error). If you're not set on using GemFire 7.0 you might want to stick with GemFire 6.6.x seeing that the JMX framework changed significantly in 7.0. If you do try 6.6.x, please let us know if that works.
