JBoss AS Addon gets NPE ----------------------- Key: FORGEPLUGINS-162 URL: https://issues.jboss.org/browse/FORGEPLUGINS-162 Project: Forge Plugins/Addons Issue Type: Bug Components: JBoss AS Plugin Reporter: Antonio Goncalves Assignee: Jérémie Lagarde Priority: Critical I've installed the latest version of Forge (2.4.2-SNAPSHOT) and JBoss AS Addon : {code} [demo]$ addon-list Currently installed addons: ... org.jboss.forge.addon:as,2.0.0-SNAPSHOT org.jboss.forge.addon:as-jboss-as7,2.0.0-SNAPSHOT org.jboss.forge.addon:as-jboss-wf8,2.0.0-SNAPSHOT org.jboss.forge.addon:as-spi,2.0.0-SNAPSHOT {code} Things work kind of ok, I manage to start JBoss, deploy app, but once in a while (I don't know how to reproduce it) I get a NPE on the logs, and then, all the {{as}} commands disappear (not TAB completion), and that's the end of the add-on. Even restarting Forge doesn't help. I need to remove and re-install the addon. {code} 19:24:01,527 SEVERE [org.jboss.forge.addon.ui.impl.command.CommandFactoryImpl] (Aesh Process Loop 2020314661) Error while checking if command org.jboss.forge.addon.as.ui.ASUndeployWizardImpl@4d75c021 isEnabled: java.lang.NullPointerException at org.jboss.forge.addon.as.ui.AbstractASWizardImpl.getSelectedProvider(AbstractASWizardImpl.java:83) at org.jboss.forge.addon.as.ui.AbstractASWizardImpl.isEnabled(AbstractASWizardImpl.java:61) at sun.reflect.GeneratedMethodAccessor238.invoke(Unknown Source) [:1.7.0_45] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [rt.jar:1.7.0_45] at java.lang.reflect.Method.invoke(Method.java:606) [rt.jar:1.7.0_45] at org.jboss.forge.furnace.proxy.ClassLoaderInterceptor$1.call(ClassLoaderInterceptor.java:59) [furnace-proxy-2.4.2-SNAPSHOT.jar:2.4.2-SNAPSHOT] at org.jboss.forge.furnace.util.ClassLoaders.executeIn(ClassLoaders.java:34) [furnace-api-2.4.2-SNAPSHOT.jar:2.4.2-SNAPSHOT] at org.jboss.forge.furnace.proxy.ClassLoaderInterceptor.invoke(ClassLoaderInterceptor.java:75) [furnace-proxy-2.4.2-SNAPSHOT.jar:2.4.2-SNAPSHOT] at org.jboss.forge.addon.as.ui.ASUndeployWizardImpl_$$_javassist_edd91fc8-6604-4157-bd0e-1803e7ea98d4.isEnabled(ASUndeployWizardImpl_$$_javassist_edd91fc8-6604-4157-bd0e-1803e7ea98d4.java) at org.jboss.forge.addon.ui.util.Commands.isEnabled(Commands.java:54) [ui-api-2.4.2-SNAPSHOT.jar:2.4.2-SNAPSHOT] at org.jboss.forge.addon.ui.impl.command.CommandFactoryImpl.getEnabledCommandNames(CommandFactoryImpl.java:77) [ui-impl-2.4.2-SNAPSHOT.jar:2.4.2-SNAPSHOT] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [rt.jar:1.7.0_45] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) [rt.jar:1.7.0_45] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [rt.jar:1.7.0_45] at java.lang.reflect.Method.invoke(Method.java:606) [rt.jar:1.7.0_45] at org.jboss.forge.furnace.proxy.ClassLoaderInterceptor$1.call(ClassLoaderInterceptor.java:59) [furnace-proxy-2.4.2-SNAPSHOT.jar:2.4.2-SNAPSHOT] at org.jboss.forge.furnace.util.ClassLoaders.executeIn(ClassLoaders.java:34) [furnace-api-2.4.2-SNAPSHOT.jar:2.4.2-SNAPSHOT] at org.jboss.forge.furnace.proxy.ClassLoaderInterceptor.invoke(ClassLoaderInterceptor.java:75) [furnace-proxy-2.4.2-SNAPSHOT.jar:2.4.2-SNAPSHOT] at org.jboss.forge.addon.ui.impl.command.CommandFactoryImpl_$$_javassist_2cbdd21c-7325-462b-9a45-1a35fe865a17.getEnabledCommandNames(CommandFactoryImpl_$$_javassist_2cbdd21c-7325-462b-9a45-1a35fe865a17.java) [ui-impl-2.4.2-SNAPSHOT.jar:2.4.2-SNAPSHOT] at org.jboss.forge.addon.shell.aesh.ForgeCommandRegistry.getForgeCommandNames(ForgeCommandRegistry.java:171) at org.jboss.forge.addon.shell.aesh.ForgeCommandRegistry.getAllCommandNames(ForgeCommandRegistry.java:162) at org.jboss.aesh.console.AeshConsoleImpl.completeCommandName(AeshConsoleImpl.java:180) at org.jboss.aesh.console.AeshConsoleImpl.access$000(AeshConsoleImpl.java:48) at org.jboss.aesh.console.AeshConsoleImpl$AeshCompletion.complete(AeshConsoleImpl.java:227) at org.jboss.aesh.console.AeshCompletionHandler.complete(AeshCompletionHandler.java:125) at org.jboss.aesh.console.AeshInputProcessor.complete(AeshInputProcessor.java:363) at org.jboss.aesh.console.AeshInputProcessor.parseOperation(AeshInputProcessor.java:148) at org.jboss.aesh.console.Console.processInternalOperation(Console.java:592) at org.jboss.aesh.console.Console.execute(Console.java:582) at org.jboss.aesh.console.Console.access$700(Console.java:60) at org.jboss.aesh.console.Console$6.run(Console.java:499) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) [rt.jar:1.7.0_45] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) [rt.jar:1.7.0_45] at java.lang.Thread.run(Thread.java:744) [rt.jar:1.7.0_45] {code}
