Hi, I'm occasionally getting the following NPE when monitoring our Cray system (Torque/ALPS): java.lang.NullPointerException at org.eclipse.ptp.rm.lml.internal.core.model.LMLNodeData.getLowerIdsAndSchemesForIds(LMLNodeData.java:64) at org.eclipse.ptp.rm.lml.internal.core.model.LMLNodeData.getLowerNodes(LMLNodeData.java:307) at org.eclipse.ptp.rm.lml.internal.core.model.TreeExpansion.expandLMLNode(TreeExpansion.java:46) at org.eclipse.ptp.rm.lml.ui.providers.NodedisplayComp.<init>(NodedisplayComp.java:357) at org.eclipse.ptp.rm.lml.ui.providers.NodedisplayCompMinSize.<init>(NodedisplayCompMinSize.java:71) at org.eclipse.ptp.rm.lml.ui.providers.NodedisplayCompMinSize.<init>(NodedisplayCompMinSize.java:95) at org.eclipse.ptp.rm.lml.ui.providers.NodedisplayView.createRootNodedisplay(NodedisplayView.java:687) at org.eclipse.ptp.rm.lml.ui.providers.NodedisplayView.goToImpName(NodedisplayView.java:340) at org.eclipse.ptp.rm.lml.ui.providers.NodedisplayView.update(NodedisplayView.java:428) at org.eclipse.ptp.rm.lml.ui.providers.NodedisplayView.update(NodedisplayView.java:402) at org.eclipse.ptp.rm.lml.ui.views.NodesView$LguiListener$3.run(NodesView.java:113) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.ui.internal.JFaceUtil$1.run(JFaceUtil.java:49) at org.eclipse.jface.util.SafeRunnable.run(SafeRunnable.java:175) at org.eclipse.ptp.rm.lml.ui.UIUtils$7.run(UIUtils.java:194) at org.eclipse.ui.internal.UILockListener.doPendingWork(UILockListener.java:164) at org.eclipse.ui.internal.UISynchronizer$3.run(UISynchronizer.java:158) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:135) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3945) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3622) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2701) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2665) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2499) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:679) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:668) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:124) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:352) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:624) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:579) at org.eclipse.equinox.launcher.Main.run(Main.java:1433) at org.eclipse.equinox.launcher.Main.main(Main.java:1409)
Created attachment 212624 [details] This patch should solve the problem for now. It checks the min-attribute in the scheme-tag to be not null.
