| 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 |
