New voidRequestSent notification type for jmx.
A void outgoing request does not expect any answer.
For a proper analysis, it must be differentiated from traditional outgoing requests.
CMTags bug Fixed
When a component is killed, on the ReplyImpl, the
REAL_REPLY_SENT notification will throw a NullPointerException
since the local body is null.
Now a not null body is required before notification.
