[jboss-osgi-issues] [JBoss JIRA] (JBOSGI-563) ClassCastException - AbstractResource cannot be cast to AbstractBundleRevision

ClassCastException - AbstractResource cannot be cast to AbstractBundleRevision ------------------------------------------------------------------------------ Key: JBOSGI-563 URL: https://issues.jboss.org/browse/JBOSGI-563 Project: JBoss OSGi Issue Type: Bug Security Level: Public(Everyone can see) Components: Core Framework Affects Versions: JBossOSGi 1.3.0 Reporter: Rico Neubauer Assignee: Thomas Diesler Labels: osgi Occurs with JBoss 7.1.2.Final (EAP) running with jbosgi-framework 1.3.0.Final Unfortunately not sure about the conditions - a vanilla JBoss does not show the symptom, I assume it depends on how bundle dependencies are defined, or on capability usages. Will try to find out more, but the following presents an issue anyway: Accessing bundles may throw a ClassCastException in: - org.jboss.osgi.framework.internal.HostBundleState#getDependentBundles() - org.jboss.osgi.framework.internal.PackageAdminPlugin.ExportedPackageImpl#getImportingBundles() - There are other places of unchecked casts to AbstractBundleRevision, but they may be OK. The following occurs when accessing the problematic bundles via felix web-console: {noformat} org.apache.felix.http.jetty WARN /system/console/bundles/0: java.lang.ClassCastException: org.jboss.osgi.resolver.spi.AbstractResource cannot be cast to org.jboss.osgi.framework.internal.AbstractBundleRevision at org.jboss.osgi.framework.internal.PackageAdminPlugin$ExportedPackageImpl.getImportingBundles(PackageAdminPlugin.java:536) at org.apache.felix.webconsole.internal.core.BundlesServlet.listImportExport(BundlesServlet.java:813) at org.apache.felix.webconsole.internal.core.BundlesServlet.bundleDetails(BundlesServlet.java:750) at org.apache.felix.webconsole.internal.core.BundlesServlet.bundleInfo(BundlesServlet.java:673) at org.apache.felix.webconsole.internal.core.BundlesServlet.writeJSON(BundlesServlet.java:568) at org.apache.felix.webconsole.internal.core.BundlesServlet.writeJSON(BundlesServlet.java:500) at org.apache.felix.webconsole.internal.core.BundlesServlet.renderContent(BundlesServlet.java:474) at org.apache.felix.webconsole.AbstractWebConsolePlugin.doGet(AbstractWebConsolePlugin.java:147) at org.apache.felix.webconsole.internal.core.BundlesServlet.doGet(BundlesServlet.java:246) at javax.servlet.http.HttpServlet.service(HttpServlet.java:734) at javax.servlet.http.HttpServlet.service(HttpServlet.java:847) at org.apache.felix.webconsole.internal.servlet.OsgiManager.service(OsgiManager.java:437) at org.apache.felix.webconsole.internal.servlet.OsgiManager.service(OsgiManager.java:384) at org.apache.felix.http.base.internal.handler.ServletHandler.doHandle(ServletHandler.java:96) at org.apache.felix.http.base.internal.handler.ServletHandler.handle(ServletHandler.java:79) at org.apache.felix.http.base.internal.dispatch.ServletPipeline.handle(ServletPipeline.java:42) at org.apache.felix.http.base.internal.dispatch.InvocationFilterChain.doFilter(InvocationFilterChain.java:49) at org.apache.felix.http.base.internal.dispatch.HttpFilterChain.doFilter(HttpFilterChain.java:33) at org.apache.felix.http.base.internal.dispatch.FilterPipeline.dispatch(FilterPipeline.java:48) at org.apache.felix.http.base.internal.dispatch.Dispatcher.dispatch(Dispatcher.java:39) at org.apache.felix.http.base.internal.DispatcherServlet.service(DispatcherServlet.java:67) at javax.servlet.http.HttpServlet.service(HttpServlet.java:847) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:511) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:390) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:182) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:765) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.Server.handle(Server.java:326) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:542) at org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:926) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:549) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:212) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:404) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:410) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:582) {noformat} Will attach a fix for those two locations.
