Description

The while block between line 329 and line 352 in https://github.com/apache/karaf/blob/master/shell/core/src/main/java/org/apache/karaf/shell/impl/console/ConsoleSessionImpl.java will never break if Exception other than EndOfFileException is thrown, e.g. StreamClosed exception.

After executing a karaf command (the commands are in a scritp which will be executed via the command source) I happened to get the Interrupted error, then the branding screen was shown, followed by infinite Stream Closed IOException. Sorry I got this phenomenon only from time to time and cannot provide stable steps to reproduce it.

Hit '<tab>' for a list of available commands
and '[cmd] --help' for help on a specific command.
Hit '<ctrl-d>' or type 'system:shutdown' or 'logout' to shutdown Karaf.
