   This regression test covers a slew of bugs in Standard MBean

   reflection.  Lots of corner cases were incorrect:

   In the MBeanInfo for a Standard MBean:

   - Boolean isX() defined an attribute as if it were boolean isX()

   - int isX() defined neither an attribute nor an operation

   When calling MBeanServer.getAttribute:

   - int get() and void getX() were considered attributes even though they

     were operations in MBeanInfo

   When calling MBeanServer.invoke:

   - Boolean isX() could not be called because it was (consistently with

     MBeanInfo) considered an attribute, not an operation
