Install JBT 4.2.0.Beta3 or CR1 (nightly) into Eclipse Luna eclipse-jee-luna-R-linux.gtk.x86_64.tar.gz 2. Launch JBT, and Central will open by itself (default) 3. Select Software/Update tab 4. Enable the "Enable Early Access" box, and click "Yes" to accept. 5. Disable the "Enable Early Access" box, and click "OK" to acknowledge. (So far, so good.) 6. Close Central, then reopen it from the coolbar icon. 7. Repeat steps 4 and 5. This time, you will see errors such as this: {code} Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench". {code} {code} org.eclipse.swt.SWTException: Widget is disposed at org.eclipse.swt.SWT.error(SWT.java:4441) at org.eclipse.swt.SWT.error(SWT.java:4356) at org.eclipse.swt.SWT.error(SWT.java:4327) at org.eclipse.swt.widgets.Widget.error(Widget.java:476) at org.eclipse.swt.widgets.Widget.getDisplay(Widget.java:562) at org.jboss.tools.central.editors.JBossCentralEditor$HeaderText$1.propertyChange(JBossCentralEditor.java:533) at org.eclipse.ui.preferences.ScopedPreferenceStore$3.run(ScopedPreferenceStore.java:382) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.ui.preferences.ScopedPreferenceStore.firePropertyChangeEvent(ScopedPreferenceStore.java:378) at org.eclipse.ui.preferences.ScopedPreferenceStore$2.preferenceChange(ScopedPreferenceStore.java:197) at org.eclipse.core.internal.preferences.EclipsePreferences$3.run(EclipsePreferences.java:896) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.preferences.EclipsePreferences.firePreferenceEvent(EclipsePreferences.java:899) at org.eclipse.core.internal.preferences.EclipsePreferences.putBoolean(EclipsePreferences.java:926) at org.jboss.tools.central.editors.SoftwarePage.handleEarlyAccessChanged(SoftwarePage.java:553) at org.jboss.tools.central.editors.SoftwarePage.access$11(SoftwarePage.java:506) at org.jboss.tools.central.editors.SoftwarePage$5.widgetSelected(SoftwarePage.java:236) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:248) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Display.sendEvent(Display.java:4486) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1388) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3831) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3441) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$9.run(PartRenderingEngine.java:1151) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:1032) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:148) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:636) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:579) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:150) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:135) 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:382) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:236) 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:483) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:648) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:603) at org.eclipse.equinox.launcher.Main.run(Main.java:1465) at org.eclipse.equinox.launcher.Main.main(Main.java:1438) {code} {code} eclipse.buildId=4.4.0.I20140606-1215 java.version=1.8.0 java.vendor=Oracle Corporation BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_US Framework arguments: -product org.eclipse.epp.package.jee.product -showLocation -Dorg.jboss.tools.vpe.loadxulrunner=false Command-line arguments: -os linux -ws gtk -arch x86_64 -product org.eclipse.epp.package.jee.product -clean -showLocation -data /home/nboldt/eclipse/workspace-clean44 -consolelog -console -debug -Dorg.jboss.tools.vpe.loadxulrunner=false {code} 8.
