Re: [jetty-users] Busy loop with: javax.net.ssl.SSLException: Received f

Greg and Simone have been chasing down the oddball case like this for
a while now..could you open this as an issue in bugs.eclipse.org under
RT/Jetty and we'll take a look.

you might want to try one of the 7.4.1 snapshots as we are close to
release and it would be interesting to see if recent work had
addressed your use case since you seem to have an environment that
triggers it.
