GLOBAL_MAX_SIZE or AMQ_GLOBAL_MAX_SIZE ?

The amq7.7 doc says  AMQ_ GLOBAL_MAX_SIZE to set broker memory.

But it is 'GLOBAL_MAX_SIZE' which actually works

Need to correct the documentation 

Already this is raised in  jira  https://issues.redhat.com/browse/CLOUD-2544  2 years ago

customer raised another one   github https://github.com/jboss-container-images/jboss-amq-7-broker-openshift-image/issues/63
