| 37 | This regression test covers a slew of bugs in Standard MBean |
| 38 | reflection. Lots of corner cases were incorrect: |
| 39 | |
| 40 | In the MBeanInfo for a Standard MBean: |
| 41 | - Boolean isX() defined an attribute as if it were boolean isX() |
| 42 | - int isX() defined neither an attribute nor an operation |
| 43 | |
| 44 | When calling MBeanServer.getAttribute: |
| 45 | - int get() and void getX() were considered attributes even though they |
| 46 | were operations in MBeanInfo |
| 47 | |
| 48 | When calling MBeanServer.invoke: |
| 49 | - Boolean isX() could not be called because it was (consistently with |
| 50 | MBeanInfo) considered an attribute, not an operation |
