Using cacao :
- build b06
- client/cacao agent on solaris sparc 5.9,
or
- client/cacao agent solaris intel 5.9
or
- client/cacao agent linux Redhat Server 2.1


The following problem can be reproduce with UnknownJmxClient example :

take the UnknownJmxClient example, but modify it to loop in case of failure, in order to try again until suceed

launch the example, but with an unknown user/password.

The connection will fail as expected with following stack each time requested, but after
several trials, connection is blocked and client never get back from connection request !

Problem has been isolated and reproduced on JMX 1.2 with remoting - see Luis.
