Test suite failures for TC 7 (MBeanUtils, host null)

[Rainer Jung]

I get test suite failures for TC 7 right now. I'm not sure whether it is 
because I changed my testing environment, but the failure seems to be 
pretty special, namely a NullPointerException in 
MBeanUtils.createObjectName() line 532.

I added some logging and the reason is, that the host returned by
Container host = context.getParent();

is null.

The MBean name for the first failure is

Catalina:type=Environment,resourcetype=Context,context=/examples,host=NULL,name=name3

(I replaced host.getName() with "NULL" when host is null) but there are 
many such failures during the test run. Not sure, but because it always 
seems to happen on destroy, it might be a lifecycle issue?

Regards,

Rainer
