Build Identifier: I20110613-1736 I am trying to install a feature I developed, which specifies a 'metaRequirement' on a plugin declaring an action. During the install phase, on Indigo I am getting this exception right after the "unsigned plugins" dialog is displayed. The exception is not fatal - refusing to close the workbench after an SWT exception leads to a successful installation. Also, the error is only seen when installing the first time on a fresh Eclipse. Updating does not show this problem. Note This does _not_ happen in Eclipse Helios, only in Indigo. Reproducible: Always Steps to Reproduce: 1. Add an Archive update site to a fresh Eclipse for C/C++ Developers installation, pointing to the provided archive 2. Select the 'Feature requiring action when installing' _only_. 3. Perform the installation, and verify that the following exception is seen: org.eclipse.swt.SWTError: Cannot initialize Drop at org.eclipse.swt.dnd.DND.error(DND.java:266) at org.eclipse.swt.dnd.DND.error(DND.java:227) at org.eclipse.swt.dnd.DropTarget.<init>(DropTarget.java:135) at org.eclipse.epp.internal.mpc.ui.wizards.MarketplaceDropAdapter.installDropTarget(MarketplaceDropAdapter.java:59) at org.eclipse.epp.internal.mpc.ui.wizards.MarketplaceDropAdapter$1.runInUIThread(MarketplaceDropAdapter.java:48) at org.eclipse.ui.progress.UIJob$1.run(UIJob.java:95) 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:4140) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3757) at org.eclipse.jface.window.Window.runEventLoop(Window.java:825) at org.eclipse.jface.window.Window.open(Window.java:801) at org.eclipse.jface.dialogs.ErrorDialog.open(ErrorDialog.java:360) at org.eclipse.equinox.internal.p2.ui.ValidationDialogServiceUI$2.run(ValidationDialogServiceUI.java:100) 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:4140) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3757) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2696) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2660) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2494) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:674) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:667) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:123) 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:344) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) 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:622) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:577) at org.eclipse.equinox.launcher.Main.run(Main.java:1410) 4. Verify that ignoring the exception and continuing the install works. Note this does NOT happen if the 'ContainerFeature' is installed (which ships the plugin containing the action in the feature itself). Also and it does NOT happen if the plugin containing the action is already installed in the target.
Created attachment 203760 [details] Two deployable features, one of which contains a metaRequirement and causes the exception to be thrown. Added zip file attachment containing an update site with two features: * A container feature shipping the plugin with the action ('ContainerFeature'). * A feature requiring the action in configure phase ('Feature requiring...'). The bug is only seen when installing the latter.
I have also noted that the exception is NOT seen if 'Contact all update sites' is unchecked before starting to install the 'Feature requiring action when installing'.

Moving it to C/CPP package as you start from an "Eclipse for C/C++ Developers"
Moving againg... this time to the Marketplace Client... the stack trace tells me that there is something going wrong with the D&D support of the MPC.
This seems to have been fixed in Indigo SR1, both for 32- and 64-bit versions. I cannot reproduce the bug anymore using: eclipse-cpp-indigo-SR1-incubation-win32 org.eclipse.epp.package.cpp.product Version: Indigo Service Release 1 Build id: 20110916-0149
Seems to be fixed.
