Hi,
Well, it looks to me like he has thrown the NoSuchMethodException himself
in his ModelMBeanImpl. This exception dexcends from Exception, thus is not
a reflection exception, and isn't caught by any of the exception
handlers/ignorers.
I don't yet understand what ModelMBeans are for... but if he changed the
missing method handling to match that of line 1620 of the MBeanServerImpl,
the problems might go away.
Further posts from Scott Stark and Marc Fleury make me think this may be
difficult to impossible. If so, we could instead change ServiceControl to
ignore MethodNotFoundExceptions as well as ReflectionExceptions. e.g.
around line 67
} catch (ReflectionException e)
{
// Not a service - ok
}
catch (NoSuchMethodException e) {
//Not a service - also ok
} catch (RuntimeMBeanException e)
Personally I am inclined to suggest putting empty methods for the
nonexistent operations in every mbean. I don't entirely understand why
this isn't in the mbean spec.
