EAP 6.1.0 different jboss-cli behaviour with automated bash scripts

Issue

In JBoss EAP 6.0 user made a set of jboss-cli support scripts using bash (on Linux).
With JBoss EAP 6.1 these scripts are working no more.

Here is an example of a script which fails

#!/bin/bash
PROFILE=$1

jboss-cli.sh -c <<EOF
batch
/profile=$PROFILE/subsystem=remoting/connector=remoting-connector:write-attribute(name=security-realm,value=ManagementRealm)
/profile=$PROFILE/subsystem=jmx/remoting-connector=jmx:add(use-management-endpoint=false)
run-batch
EOF

It seems that with EAP 6.1 jboss-cli.sh the stdin stream is not correctly read from batch lines, so the shell script is blocking may be still waiting for input. Ctrl-C on console is the only way to stop it.

• What happened to the jboss-cli.sh?
• What's the difference between 6.0 and 6.1 jboss-cli?
• How should we write batch scripts to make them compatible with ALL current and future versions of jboss-cli?
