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
