NullPointerException in eclipse in Eclipse itself at PartServiceImpl.internalFixContext
Solution 1
There is a bug filed for Eclipse
:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=385680
You could try restarting Eclipse
, it helped the original poster of the issue there.
Solution 2
Better you update your eclipse by clicking it on help >> check for updates, also you can start eclipse by entering command in command prompt eclipse -clean.
Hope this will help you.
Solution 3
I have also encountered this error . Just i opened the new window ie Window -> New Window in eclipse .Then , I closed my old window. This solved my problem.
Solution 4
hi,that maybe the project's problem,
chose the project and setting you eclipse:
project -> clean...
Solution 5
After exiting eclipse I moved .eclipse (found in the user's home directory) to .eclipse.old (just in case I may have had to undo). The error does not show up any more and my projects are working fine after restarting eclipse.
Caution: I have a simple setup and this may not be the best for environments with advanced settings.
I am posting this as a separate answer as previously listed methods did not work for me.

I have a problem about eclipse IDE, I can't open any file in my work space; if I try to open file, eclipse will alert the following error dialog
"An error has occurred. See error log for more details. java.lang.NullPointerException"
I go to see .log file in .meta at workspace and I see a paragraph in the file like this:
!ENTRY org.eclipse.jface 4 2 2557-04-09 11:40:49.422 !MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.jface". !STACK 0 java.lang.NullPointerException at org.eclipse.e4.ui.internal.workbench.PartServiceImpl.internalFixContext(PartServiceImpl.java:380) at org.eclipse.e4.ui.internal.workbench.PartServiceImpl.bringToTop(PartServiceImpl.java:341) at org.eclipse.e4.ui.internal.workbench.PartServiceImpl.showPart(PartServiceImpl.java:1029) at org.eclipse.ui.internal.WorkbenchPage.busyOpenEditor(WorkbenchPage.java:3047) at org.eclipse.ui.internal.WorkbenchPage.access$22(WorkbenchPage.java:2969) at org.eclipse.ui.internal.WorkbenchPage$8.run(WorkbenchPage.java:2951) at org.eclipse.swt.custom.BusyIndicator.showWhile(BusyIndicator.java:70) at org.eclipse.ui.internal.WorkbenchPage.openEditor(WorkbenchPage.java:2947) at org.eclipse.ui.internal.WorkbenchPage.openEditor(WorkbenchPage.java:2911) at org.eclipse.ui.internal.WorkbenchPage.openEditor(WorkbenchPage.java:2902) at org.eclipse.ui.ide.IDE.openEditor(IDE.java:655) at org.eclipse.ui.ide.IDE.openEditor(IDE.java:614) at org.eclipse.jdt.internal.ui.javaeditor.EditorUtility.openInEditor(EditorUtility.java:360) at org.eclipse.jdt.internal.ui.javaeditor.EditorUtility.openInEditor(EditorUtility.java:167) at org.eclipse.jdt.ui.actions.OpenAction.run(OpenAction.java:249) at org.eclipse.jdt.ui.actions.OpenAction.run(OpenAction.java:228) at org.eclipse.jdt.ui.actions.SelectionDispatchAction.dispatchRun(SelectionDispatchAction.java:275) at org.eclipse.jdt.ui.actions.SelectionDispatchAction.run(SelectionDispatchAction.java:251) at org.eclipse.jdt.internal.ui.packageview.PackageExplorerActionGroup.handleOpen(PackageExplorerActionGroup.java:376) at org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart$4.open(PackageExplorerPart.java:538) at org.eclipse.ui.OpenAndLinkWithEditorHelper$InternalListener.open(OpenAndLinkWithEditorHelper.java:48) at org.eclipse.jface.viewers.StructuredViewer$2.run(StructuredViewer.java:866) 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.jface.viewers.StructuredViewer.fireOpen(StructuredViewer.java:864) at org.eclipse.jface.viewers.StructuredViewer.handleOpen(StructuredViewer.java:1152) at org.eclipse.jface.viewers.StructuredViewer$6.handleOpen(StructuredViewer.java:1256) at org.eclipse.jface.util.OpenStrategy.fireOpenEvent(OpenStrategy.java:275) at org.eclipse.jface.util.OpenStrategy.access$2(OpenStrategy.java:269) at org.eclipse.jface.util.OpenStrategy$1.handleEvent(OpenStrategy.java:309) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1053) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:4169) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3758) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$9.run(PartRenderingEngine.java:1053) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:942) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:86) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:588) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:543) 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:353) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:180) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:629) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:584) at org.eclipse.equinox.launcher.Main.run(Main.java:1438) at org.eclipse.equinox.launcher.Main.main(Main.java:1414)
