Key input issue on Karaf Console after log:tail command

After installing odl-nsf-all, odl-openflowplugin-all, odl-adsal-compatibility-all, and odl-vtn-manager-all executing a "log:tail" in the karaf cli yields to an error message/automatic disconnect from the karaf cli. A workaround is to add the Grep option and the error/disconnect will not occur "log:tail |grep vtn"

i.e.
opendaylight-user@root>log:tail
