Description
1. There's a method annotated with @Before in the abstract test class. Most concrete test classes also have methods annotated with @Before which inside their body also call the the setUp() method from the abstract class. During a build both methods (the one from the abstract class and the one from the concrete one) are called and the one from the subclass is called first :|. This method setups mbean server and then checks if required mbeans have been registered. After it completes, the the setUp() method from the super class is called directly. It creates a new mbean server - overrides the previous one. The new one is not prepared to be used inside the test method as mbeans haven't been registered yet and there's no code that would wait for those mbeans to be registered. This causes an exception to be thrown in various tests and build to fail. Example:

2. FrameworkMBeanTest does not wait for the FrameworkMBean at all.
3. Tests wait 5 seconds for mbeans to be registered. This is often not sufficient enough.
4. Some other minor changes are required.
A patch coming soon.
Unfortunately, the list of JMX itests issues provided above is not complete. Additional experiments need to be carried out and some other fixes will probably be required.
