--------------------------------------------------------------------

As a work around we can use a simple, CLI command for checking if the cluster is ready:
{code}
/opt/jboss/infinispan-server/bin/ispn-cli.sh -c --controller=$(hostname -i):9990 '/subsystem=datagrid-infinispan/cache-container=clustered/distributed-cache=*:read-attribute(name=cache-rebalancing-status)' | awk '/result/{gsub("\"", "", $3); print $3}' | awk '{if(NR>1)print}' | grep -v 'PENDING\|IN_PROGRESS\|SUSPENDED'

Returns non 0 if rebalaning is in progress
{code}

And there is also a work around for a liveness check:
{code}
/opt/jboss/infinispan-server/bin/ispn-cli.sh -c --controller=$(hostname -i):9990 '/:read-attribute(name=server-state)' | awk '/result/{gsub("\"", "", $3); print $3}' | grep running

returns non 0 if is *not* running
{code}

returns 0 if is *not* running!
