The code is:
public int hashCode()
{
int result;
result = objectName.hashCode();
result = 29 * result + handback.hashCode();
result = 29 * result + filter.hashCode();
return result;
}
This code requires that the filter be non-null, or a NullPointerException will be
raised.
If I have an MBeanLocator, then if I use the following idiom:
locator.getServer().addNotificationListener(locator.getObjectName(), aListener, null,
null);
I will get a NullPointerException if the MBeanServer is actually remote and the
implementation talks to it through a dynamic proxy, but it will work fine if the
MBeanServer is local and the implementation talks to it directly. This clearly
violates location transparency and disagrees with the interface for a local MBean,
where null filters are explicitly allowed.
I would appreciate a fix, as it will be awhile before I can move to 4.0. Thanks.
