When jboss_init_redhat.sh is called with JBOSSSH set to a custom shell, additionally defined custom variables JBOSS_CONF and JBOSS_BIND_ADDR are being ignored.

I suggest that:

JBOSSSH=${JBOSSSH:-"$JBOSS_HOME/bin/run.sh -c $JBOSS_CONF $JBOSS_BIND_ADDR"}

is changed to:

JBOSSSH=${JBOSSSH:-"$JBOSS_HOME/bin/run.sh}

and the proper start command variable (NOT shell variable) includes options. For example:

JBOSS_CMD_START="cd $JBOSS_HOME/bin; $JBOSSSH -c $JBOSS_CONF $JBOSS_BIND_ADDR"
