Handle gracefully situations when MBeans are not available #30

Open joerghoh opened 11 years ago

joerghoh commented 11 years ago

In many cases we have situations where 2 different processes interfere:

Instantiation of the MBeanStatusProvider based on the config nodes
Startup of the jmx-extension bundle.

In case the config is handled first, it requires MBeans which are not there yet, resulting in errors and there's no recovery possible.

Therefor I will modify the MBeanStatusProvider like this:

The creation of the connection to the MBean will be moved off the activator.
on every call of getStatus() all check for the availability of the mbean will be triggered. If the MBean is not available, it will return "UNKNOWN".
