In 6.2, a new rest-all role is required to access the REST remote API (and therefor also the remote Java client through REST). The remote Java client should give a meaningful error message if the user isn't authorized. In 6.2.0.ER4, it is returning: org.kie.remote.client.api.exception.RemoteCommunicationException: Unable to retrieve content from response at org.kie.services.client.api.command.AbstractRemoteCommandObject.execu teRestCommand(AbstractRemoteCommandObject.java:425) at org.kie.services.client.api.command.AbstractRemoteCommandObject.execu teCommand(AbstractRemoteCommandObject.java:159) at org.kie.services.client.api.command.KieSessionClientCommandObject.sta rtProcess(KieSessionClientCommandObject.java:276) at com.redhat.bpms.examples.mortgage.CreateProcesses.populateSamples(Cre ateProcesses.java:57) at com.redhat.bpms.examples.mortgage.CreateProcesses.main(CreateProcesse s.java:47) Caused by: org.kie.remote.common.rest.KieRemoteHttpRequestException: Unable to r etrieve input stream of response at org.kie.remote.common.rest.KieRemoteHttpRequest.responseStream(KieRem oteHttpRequest.java:1378) at org.kie.remote.common.rest.KieRemoteHttpRequest.responseBuffer(KieRem oteHttpRequest.java:1396) at org.kie.remote.common.rest.KieRemoteHttpRequest.responseBody(KieRemot eHttpRequest.java:1338) at org.kie.remote.common.rest.KieRemoteHttpRequest.access$2100(KieRemote HttpRequest.java:117) at org.kie.remote.common.rest.KieRemoteHttpRequest$5.body(KieRemoteHttpR equest.java:1304) at org.kie.services.client.api.command.AbstractRemoteCommandObject.execu teRestCommand(AbstractRemoteCommandObject.java:407) ... 4 more Caused by: java.net.HttpRetryException: cannot retry due to server authenticatio n, in streaming mode at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLCo nnection.java:1637) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLCon nection.java:1440) at java.net.HttpURLConnection.getResponseCode(HttpURLConnection.java:480 ) at org.kie.remote.common.rest.KieRemoteHttpRequest.responseCode(KieRemot eHttpRequest.java:1318) at org.kie.remote.common.rest.KieRemoteHttpRequest.post(KieRemoteHttpReq uest.java:719) at org.kie.services.client.api.command.AbstractRemoteCommandObject.execu teRestCommand(AbstractRemoteCommandObject.java:362) ... 4 more
