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
