I have a project shared using the Pessimistic Filesystem Provider included in the eclipse examples. When I run the Generate Entities action (where I leave teh default source project for the current project, and specify a new package) and click Finish, I get an error dialog with the following exception, and no entities are generated: java.lang.IllegalArgumentException: Attempted to beginRule: R/, does not match outer scope rule: P/prohectoTeam at org.eclipse.core.runtime.Assert.isLegal(Unknown Source) at org.eclipse.core.internal.jobs.ThreadJob.illegalPush(Unknown Source) at org.eclipse.core.internal.jobs.ThreadJob.push(Unknown Source) at org.eclipse.core.internal.jobs.ImplicitJobs.begin(Unknown Source) at org.eclipse.core.internal.jobs.JobManager.beginRule(Unknown Source) at org.eclipse.core.internal.resources.WorkManager.checkIn(Unknown Source) at org.eclipse.core.internal.resources.Workspace.prepareOperation(Unknown Source) at org.eclipse.core.internal.resources.Workspace.run(Unknown Source) at org.eclipse.jdt.internal.core.JavaModelOperation.runOperation(Unknown Source) at org.eclipse.jdt.internal.core.PackageFragment.createCompilationUnit(Unknown Source) at org.eclipse.jpt.gen.internal.EntityGenerator.generateSourceFile(Unknown Source) at org.eclipse.jpt.gen.internal.EntityGenerator.generateEntity_(Unknown Source) at org.eclipse.jpt.gen.internal.EntityGenerator.generateEntity(Unknown Source) at org.eclipse.jpt.gen.internal.EntityGenerator.generateEntity(Unknown Source) at org.eclipse.jpt.gen.internal.PackageGenerator.buildEntity(Unknown Source) at org.eclipse.jpt.gen.internal.PackageGenerator.generateEntities(Unknown Source) at org.eclipse.jpt.gen.internal.PackageGenerator.generateEntities(Unknown Source) at org.eclipse.jpt.ui.internal.platform.base.EntitiesGenerator$GenerateEntitiesRunnable.runInWorkspace(Unknown Source) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(Unknown Source) at org.eclipse.core.internal.jobs.Worker.run(Unknown Source)

I've entered a bug against JDT for having a *very* broad scheduling rule for creating a compilation unit. Our easiest fix is of course for them to narrow that rule. We could also work around this by using the workspace root as a scheduling rule for generating entities.
I was unable to reproduce with the synchronize classes operation, only with generating entities. Are you still able to reproduce this part of it, and if so, can you give some more detailed steps?
We fixed this recently in bug 290061 so I am marking this as a duplicate *** This bug has been marked as a duplicate of bug 290061 ***
