Exception when using bin/activemq query or list ...

[Ravi <ex...@gmail.com>]

The command line bin/activemq list throws the following error (we first
tried to access the broker through web console, but no response) ...

Anyone know what the problem might be. Is the broker state hosed and we need
to restart ?
