> {{FsShell}}'s top level exception handler catches and displays exceptions.  Unfortunately it displays only the first line of an exception, which means an unexpected {{RuntimeExceptions}} like {{NullPointerException}} only display "{{cmd: NullPointerException}}".  This user has no context to understand and/or accurately report the issue.
