Just in case: client-server batch tests are there. It is funny that Ant script looks as if batchtestserver was calling Bug54685.jmx, however in fact it calls BatchTestLocal.jmx.
The way to execute client-server test is "gw batchServerBatchTestLocal" (the naming is "batchServer"+jmxName) You can find the list of all batch tests via gw :src:dist-check:tasks or via cd src/dist-check && gw tasks. Vladimir
