jboss-cli.sh throws NPE in batch mode with certain commands ----------------------------------------------------------- Key: WFLY-1512 URL: https://issues.jboss.org/browse/WFLY-1512 Project: WildFly Issue Type: Bug Components: CLI Affects Versions: 8.0.0.Alpha2 Environment: Linux 3.9.4-200.fc18.x86_64 #1 SMP Fri May 24 20:10:49 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Reporter: Thomas Hauser Assignee: Alexey Loubyansky When the jboss-cli.sh (and by extension, the CommandContext API in java) is given certain commands while not connected to the client, an unhandled NPE is thrown from org.jboss.as.cli.handlers.GenericTypeOperationHandler.getOperationDescription(GenericTypeOperationHandler.java:886) Certain other commands succeed: [disconnected / #] /subsystem=datasources/jdbc-driver=ibmdb2:add(driver-name=ibmdb2,driver-module-name=com.ibm.db2) #1 /subsystem=datasources/jdbc-driver=ibmdb2:add(driver-name=ibmdb2,driver-module-name=com.ibm.db2) The line in question is here, in org.jboss.as.cli.handlers.GenericTypeOperationHandler: result = ctx.getModelControllerClient().execute(request); At the time of this call, the client field of the context is null; therefore, calling the execute method results in this NPE. This code is not hit with the /subsystem command because of some logic I see in CommandContextImpl.
