restarting jmx server makes hibernate entities stay unavailable
---------------------------------------------------------------
Key: JOPR-81
URL: https://jira.jboss.org/jira/browse/JOPR-81
Project: Jopr
Issue Type: Bug
Components: Plugin - Hibernate
Reporter: John Mazzitelli
Assignee: John Mazzitelli
Fix For: 2.2
How to repeat:
See the steps for rhq-1600. After these steps, ctrl-C the java command you ran, wait a
minute, and restart the same command as before.
Now browse back to the hibernate entities for helloworld and notice they stay red
forever.

Stepping throught the code, this is caused by this NPE:
Caused by: java.lang.NullPointerException

The debug output is "Call to
org.rhq.plugins.hibernate.EntityComponent.getAvailability() with args [] failed."
MBeanResourceComponent line 100-101 is:
protected void loadBean() {
Configuration pluginConfig = this.resourceContext.getPluginConfiguration();
The resourceContent is null. This is due to misusing the MBeanServerComponent API.
(this was moved over from http://jira.rhq-project.org/browse/RHQ-1601 since this is Jopr
plugin related)
