[jbosscache-dev] Usage of Option override

[Manik Surtani]

cache_.getInvocationContext().getOptionOverrides 
().setForceDataGravitation(true);
Object obj = cache_.get(fqn, key);
cache_.getInvocationContext().getOptionOverrides 
().setForceDataGravitation(false);

Guaranteed not to get a null when you call getInvocationContext() or  
getOptionOverrides().
