Using I20101012-0800, when importing a project set, the error log gets filled with stack traces like this: java.lang.IllegalStateException: Preference node "org.eclipse.core.net" has been removed. at org.eclipse.core.internal.preferences.EclipsePreferences.checkRemoved(EclipsePreferences.java:157) at org.eclipse.core.internal.preferences.EclipsePreferences.internalGet(EclipsePreferences.java:513) at org.eclipse.core.internal.preferences.EclipsePreferences.getBoolean(EclipsePreferences.java:372) at org.eclipse.core.internal.net.PreferenceManager.migrateUpdateHttpProxy(PreferenceManager.java:314) at org.eclipse.core.internal.net.PreferenceManager.migrateInstanceScopePreferences(PreferenceManager.java:266) at org.eclipse.core.internal.net.ProxyManager.migrateInstanceScopePreferences(ProxyManager.java:407) at org.eclipse.core.internal.net.PreferenceModifyListener.preApply(PreferenceModifyListener.java:27) at org.eclipse.core.internal.preferences.PreferencesService$4.run(PreferencesService.java:449) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.preferences.PreferencesService.firePreApplyEvent(PreferencesService.java:452) at org.eclipse.core.internal.preferences.PreferencesService.applyPreferences(PreferencesService.java:122) at org.eclipse.core.internal.resources.ProjectPreferences.read(ProjectPreferences.java:234) at org.eclipse.core.internal.resources.ProjectPreferences.updatePreferences(ProjectPreferences.java:302) at org.eclipse.core.internal.resources.File.updateMetadataFiles(File.java:414) at org.eclipse.core.internal.resources.File.internalSetContents(File.java:326) at org.eclipse.core.internal.resources.File.create(File.java:163) at org.eclipse.core.internal.resources.File.create(File.java:196) at org.eclipse.team.internal.ccvs.core.resources.EclipseFile.setContents(EclipseFile.java:184) at org.eclipse.team.internal.ccvs.core.client.Session.receiveFile(Session.java:801) at org.eclipse.team.internal.ccvs.core.client.UpdatedHandler.receiveTargetFile(UpdatedHandler.java:119) at org.eclipse.team.internal.ccvs.core.client.UpdatedHandler.handle(UpdatedHandler.java:100) at org.eclipse.team.internal.ccvs.core.client.Request.executeRequest(Request.java:218) at org.eclipse.team.internal.ccvs.core.client.Command.doExecute(Command.java:413) at org.eclipse.team.internal.ccvs.core.client.Checkout.doExecute(Checkout.java:159) at org.eclipse.team.internal.ccvs.core.client.CheckoutWithOverwrite.doExecute(CheckoutWithOverwrite.java:52) at org.eclipse.team.internal.ccvs.core.client.Command$1.run(Command.java:326) at org.eclipse.team.internal.ccvs.core.resources.EclipseSynchronizer.run(EclipseSynchronizer.java:1481) at org.eclipse.team.internal.ccvs.core.resources.EclipseResource$2.run(EclipseResource.java:262) at org.eclipse.core.internal.resources.Workspace.run(Workspace.java:1975) at org.eclipse.team.internal.ccvs.core.resources.EclipseResource.run(EclipseResource.java:259) at org.eclipse.team.internal.ccvs.core.client.Command.execute(Command.java:338) at org.eclipse.team.internal.ccvs.ui.operations.CheckoutProjectOperation.performCheckout(CheckoutProjectOperation.java:272) at org.eclipse.team.internal.ccvs.ui.operations.CheckoutProjectOperation$2.run(CheckoutProjectOperation.java:171) at org.eclipse.team.internal.ccvs.core.resources.EclipseSynchronizer.run(EclipseSynchronizer.java:1481) at org.eclipse.team.internal.ccvs.ui.operations.CheckoutProjectOperation.checkout(CheckoutProjectOperation.java:169) at org.eclipse.team.internal.ccvs.ui.operations.CheckoutMultipleProjectsOperation.checkout(CheckoutMultipleProjectsOperation.java:58) at org.eclipse.team.internal.ccvs.ui.operations.CheckoutOperation.checkout(CheckoutOperation.java:47) at org.eclipse.team.internal.ccvs.ui.operations.CheckoutOperation.execute(CheckoutOperation.java:32) at org.eclipse.team.internal.ccvs.ui.operations.CVSOperation.run(CVSOperation.java:79) at org.eclipse.team.internal.ui.actions.JobRunnableContext.run(JobRunnableContext.java:144) at org.eclipse.team.internal.ui.actions.JobRunnableContext$ResourceJob.runInWorkspace(JobRunnableContext.java:72) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)
Created attachment 180791 [details] fix I can reproduce this issue when I import preferences a second time. When I import preferences to Eclipse with a clean configuration, first import is passed without this exception. I have attached a fix.
Created attachment 180805 [details] improved fix
I get this with these simple steps: 1. start new workspace 2. check out a project from CVS Caused by bad fix for bug 242057. Setting to 'major' since "Preference node "org.eclipse.core.net" has been removed" sounds scary.
Yes, you are right that it sounds scary :). Anyway, I have attached fix for this bug and now it is waiting for Szymon's review.
I also got it checking out from CVS WTP bundles.
Released in HEAD.
