The bug doesn't cause Jetty to > stop responding altogether, some fetches go through but a lot of them throw > exceptions and eventually fail. The only way we have found to get the TT out > of this state is to restart the TT. This jira is to catch this particular > exception (or perhaps a configurable regex) and handle it in an automated way > to either blacklist or shutdown the TT after seeing it a configurable number > of them. -- This message is automatically generated by JIRA.
