Build Identifier: Whenever I shut down the IDE, after opening Index View, I get a BundleException which is caused due to Locked Paging Strategy Pages. It Happens only if I have opened Index View before shutting down the IDE. This problem persists even if, Index View was opened and then closed. But, if the Index View is not at all opened in the IDE lifecycle. The stacktrace is as follows:- org.osgi.framework.BundleException: Exception in org.eclipse.emf.query.index.Activator.stop() of bundle org.eclipse.emf.query2.index. at org.eclipse.osgi.framework.internal.core.BundleContextImpl.stop(BundleContextImpl.java:863) at org.eclipse.osgi.framework.internal.core.BundleHost.stopWorker(BundleHost.java:501) at org.eclipse.osgi.framework.internal.core.AbstractBundle.suspend(AbstractBundle.java:550) at org.eclipse.osgi.framework.internal.core.Framework.suspendBundle(Framework.java:1097) at org.eclipse.osgi.framework.internal.core.StartLevelManager.decFWSL(StartLevelManager.java:597) at org.eclipse.osgi.framework.internal.core.StartLevelManager.doSetStartLevel(StartLevelManager.java:257) at org.eclipse.osgi.framework.internal.core.StartLevelManager.shutdown(StartLevelManager.java:215) at org.eclipse.osgi.framework.internal.core.InternalSystemBundle.suspend(InternalSystemBundle.java:266) at org.eclipse.osgi.framework.internal.core.Framework.shutdown(Framework.java:690) at org.eclipse.osgi.framework.internal.core.Framework.close(Framework.java:588) at org.eclipse.core.runtime.adaptor.EclipseStarter.shutdown(EclipseStarter.java:415) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:198) 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:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) at org.eclipse.equinox.launcher.Main.main(Main.java:1383) Caused by: java.lang.IllegalStateException: Paging strategy has locked pages at org.eclipse.emf.query.index.internal.impl.PagingStrategyImpl.flush(PagingStrategyImpl.java:334) at org.eclipse.emf.query.index.internal.impl.PagingResourceDescriptorMap.flush(PagingResourceDescriptorMap.java:105) at org.eclipse.emf.query.index.internal.impl.PageableIndexImpl.save(PageableIndexImpl.java:125) at org.eclipse.emf.query.index.IndexFactory.dumpIndexes(IndexFactory.java:97) at org.eclipse.emf.query.index.Activator.stop(Activator.java:51) at org.eclipse.osgi.framework.internal.core.BundleContextImpl$2.run(BundleContextImpl.java:843) at java.security.AccessController.doPrivileged(Native Method) at org.eclipse.osgi.framework.internal.core.BundleContextImpl.stop(BundleContextImpl.java:836) ... 19 more Root exception: java.lang.IllegalStateException: Paging strategy has locked pages at org.eclipse.emf.query.index.internal.impl.PagingStrategyImpl.flush(PagingStrategyImpl.java:334) at org.eclipse.emf.query.index.internal.impl.PagingResourceDescriptorMap.flush(PagingResourceDescriptorMap.java:105) at org.eclipse.emf.query.index.internal.impl.PageableIndexImpl.save(PageableIndexImpl.java:125) at org.eclipse.emf.query.index.IndexFactory.dumpIndexes(IndexFactory.java:97) at org.eclipse.emf.query.index.Activator.stop(Activator.java:51) at org.eclipse.osgi.framework.internal.core.BundleContextImpl$2.run(BundleContextImpl.java:843) at java.security.AccessController.doPrivileged(Native Method) at org.eclipse.osgi.framework.internal.core.BundleContextImpl.stop(BundleContextImpl.java:836) at org.eclipse.osgi.framework.internal.core.BundleHost.stopWorker(BundleHost.java:501) at org.eclipse.osgi.framework.internal.core.AbstractBundle.suspend(AbstractBundle.java:550) at org.eclipse.osgi.framework.internal.core.Framework.suspendBundle(Framework.java:1097) at org.eclipse.osgi.framework.internal.core.StartLevelManager.decFWSL(StartLevelManager.java:597) at org.eclipse.osgi.framework.internal.core.StartLevelManager.doSetStartLevel(StartLevelManager.java:257) at org.eclipse.osgi.framework.internal.core.StartLevelManager.shutdown(StartLevelManager.java:215) at org.eclipse.osgi.framework.internal.core.InternalSystemBundle.suspend(InternalSystemBundle.java:266) at org.eclipse.osgi.framework.internal.core.Framework.shutdown(Framework.java:690) at org.eclipse.osgi.framework.internal.core.Framework.close(Framework.java:588) at org.eclipse.core.runtime.adaptor.EclipseStarter.shutdown(EclipseStarter.java:415) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:198) 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:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) at org.eclipse.equinox.launcher.Main.main(Main.java:1383) Reproducible: Always Steps to Reproduce: 1. Open Index View. 2. Expand Resource Index Node. 3. Expand any of the the Resource Descriptor Node. 4. Close the IDE.
Created attachment 192794 [details] Releases the Locked Resource Descriptors This Exception was occuring because in Index View, to retrieve the EObject Tables, incoming Link Tables, and Outgoing Tables, an acquire() was called on the ResourceDescriptors, but these descriptors were not released after retrieving the local tables. An addition in the code to release() the ResourceDescriptor solves the problem.
