Currently when you set the Credentials (password) on a JMX server resource you see the password you are typing in the browser. This config prop should be of type password, similar to the Credentials prop on JBAS instances
JMX resource's "Credentials" conn prop now shows asterisks as you type, not the actual characters. rev2522.
This bug was previously known as http://jira.rhq-project.org/browse/RHQ-1057
