From a programatic perspective, there's really no way for me to know that a runtime has just been renamed.

AssertionFailedException invoking menu on a server. --------------------------------------------------- Key: JBIDE-21199 URL: https://issues.jboss.org/browse/JBIDE-21199 Project: Tools (JBoss Tools) Issue Type: Bug Components: server Affects Versions: 4.4.0.Alpha1 Reporter: Viacheslav Kabanovich Assignee: Rob Stryker Priority: Minor Fix For: 4.3.1.Beta1, 4.4.0.Alpha1 1. Create a server with a JBoss runtime. 2. Make sure that context menu is invoked without exceptions. 3. Open Preferences/Server/Runtime Environments and rename the runtime environment bound to the server. 4. Invoke contex menu. Menu is opened, but there is logged exception: {code} !ENTRY org.eclipse.ui.navigator 4 2 2015-12-07 14:45:35.604 !MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.navigator". !STACK 0 org.eclipse.core.runtime.AssertionFailedException: null argument: at org.eclipse.core.runtime.Assert.isNotNull(Assert.java:85) at org.eclipse.core.runtime.Assert.isNotNull(Assert.java:73) at org.eclipse.core.runtime.Path.initialize(Path.java:641) at org.eclipse.core.runtime.Path.<init>(Path.java:238) at org.eclipse.core.runtime.Path.<init>(Path.java:186) at org.jboss.tools.as.core.server.controllable.subsystems.internal.LocalDeploymentOptionsController.makeRelative(LocalDeploymentOptionsController.java:44) at org.jboss.tools.as.core.server.controllable.subsystems.internal.LocalDeploymentOptionsController.getDeployFolder(LocalDeploymentOptionsController.java:68) at org.jboss.tools.as.core.server.controllable.systems.AbstractJBossDeploymentOptionsController.getDeploymentsRootFolder(AbstractJBossDeploymentOptionsController.java:78) at org.jboss.ide.eclipse.as.ui.subsystems.internal.LocalExploreBehavior.getPath(LocalExploreBehavior.java:105) at org.jboss.ide.eclipse.as.ui.subsystems.internal.LocalExploreBehavior.getDeployDirectory(LocalExploreBehavior.java:62) at org.jboss.ide.eclipse.as.ui.subsystems.internal.LocalExploreBehavior.canExploreServer(LocalExploreBehavior.java:81) at org.jboss.ide.eclipse.as.ui.subsystems.internal.LocalExploreBehavior.canExplore(LocalExploreBehavior.java:34) at org.jboss.tools.as.wst.server.ui.xpl.ExploreActionProvider.fillContextMenu(ExploreActionProvider.java:102) at org.eclipse.ui.navigator.NavigatorActionService$2.run(NavigatorActionService.java:225) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.ui.navigator.NavigatorActionService.addCommonActionProviderMenu(NavigatorActionService.java:219) at org.eclipse.ui.navigator.NavigatorActionService.fillContextMenu(NavigatorActionService.java:174) at org.eclipse.ui.navigator.CommonNavigatorManager.fillContextMenu(CommonNavigatorManager.java:267) at org.eclipse.ui.navigator.CommonNavigatorManager$3.menuAboutToShow(CommonNavigatorManager.java:283) at org.eclipse.jface.action.MenuManager.fireAboutToShow(MenuManager.java:333) at org.eclipse.jface.action.MenuManager.handleAboutToShow(MenuManager.java:466) at org.eclipse.jface.action.MenuManager.access$1(MenuManager.java:461) at org.eclipse.jface.action.MenuManager$2.menuShown(MenuManager.java:493) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:255) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Display.sendEvent(Display.java:4481) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1327) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1351) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1332) at org.eclipse.swt.widgets.Menu._setVisible(Menu.java:198) at org.eclipse.swt.widgets.Display.runPopups(Display.java:3861) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3420) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$4.run(PartRenderingEngine.java:1127) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:337) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:1018) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:156) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:654) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:337) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:598) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:150) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:139) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:134) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:104) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:380) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:235) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:669) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:608) at org.eclipse.equinox.launcher.Main.run(Main.java:1515) at org.eclipse.equinox.launcher.Main.main(Main.java:1488) {code} I think we should prevent that exception. 5. Open the server in editor. Its 'Runtime Environment' is empty, which means that server lost connection to the renamed environment. Can we do something to prevent it, or is it an upstream issue, or is it an expected behavior?
