This was a snipped of the decoded stream captured w/ tshark.
Below you'll see the streams which caused the problem (some parts
of the header have been shortened/modifyed by me).
In the capture I had more requests and replys which worked, but
these had not "Java" in the User-Agent line.
Is there an option to send only "Basic" auth-requests to clients
which are identified as java applets? Maybe this could help
solving this issue.
