Error description

  • A JAX-WS client can programmatically change the endpoint
    address URL where its requests are sent.
    
    Problems can occur if the URLs share the same short hostname
    and request URI. For example, the client first sends the
    request to http://lilygirl:9080/Test/HelloWorld. Then, the
    client changes the endpoint address so that the request goes to
    http://lilygirl.austin.ibm.com/Test/HelloWorld.
    
    The two URLs are different, but share the same short name of
    the host (lilygirl) and the same request URI
    (Test/HelloWorld). The JAX-WS runtime might mistakenly treat
    the two URLs the same, and therefore might return a previously
    cached connection object for the incorrect URL. This can
    result in the request going to the wrong endpoint.

Problem conclusion

  • The JAX-WS runtime was corrected to properly differentiate
    between unique URLs.
