Bug Description:
  It looks like the current implementation of
  ModelMBeanInfoSupport#getDescriptors(String) is broken.
  Calling this method with the descriptorType MMB (=mbean) will
  always lead into a IllegalArgumentException. The cause of this
  bug is a possibly broken if/else if statement.

Steps to Reproduce (be specific):
  Call ModelMBeanInfoSupport#getDescriptors(String) with type "mbean"
  or execute the provided testcase.(testcase.zip)
