[jboss-jira] [JBoss JIRA] (WFLY-6669) Classloader leak trigerred by DOMNormalizer#abort in xercesImpl-2.11.0.SP4

Classloader leak trigerred by DOMNormalizer#abort in xercesImpl-2.11.0.SP4 -------------------------------------------------------------------------- Key: WFLY-6669 URL: https://issues.jboss.org/browse/WFLY-6669 Project: WildFly Issue Type: Bug Components: XML Frameworks Affects Versions: 10.0.0.Final Reporter: Mathieu Lachance Assignee: Jason Greene Priority: Critical XERCESJ-1667 is a fix that was incorporated in the SVN trunk of the apache xerces project. Though it was never ported back in JBoss/Xerces github. In our case, the classloader leak is triggered by the OpenSAML library which depends on Xerces, but lets be honest, this could have been anything. {code} 15:08:11.554 [stderr] java.lang.RuntimeException.<init>(RuntimeException.java:51) 15:08:11.555 [stderr] at org.apache.xerces.dom.DOMNormalizer.<clinit>(DOMNormalizer.java:155) 15:08:11.555 [stderr] at org.apache.xml.serialize.DOMSerializerImpl.verify(DOMSerializerImpl.java:973) 15:08:11.555 [stderr] at org.apache.xml.serialize.DOMSerializerImpl.prepareForSerialization(DOMSerializerImpl.java:910) 15:08:11.555 [stderr] at org.apache.xml.serialize.DOMSerializerImpl.write(DOMSerializerImpl.java:692) 15:08:11.555 [stderr] at org.opensaml.xml.util.XMLHelper.writeNode(XMLHelper.java:892) 15:08:11.556 [stderr] at org.opensaml.xml.util.XMLHelper.writeNode(XMLHelper.java:872) 15:08:11.556 [stderr] at org.opensaml.xml.util.XMLHelper.nodeToString(XMLHelper.java:834) 15:08:11.556 [stderr] at org.opensaml.xml.XMLConfigurator.load(XMLConfigurator.java:159) 15:08:11.556 [stderr] at org.opensaml.xml.XMLConfigurator.load(XMLConfigurator.java:143) 15:08:11.556 [stderr] at org.opensaml.DefaultBootstrap.initializeXMLTooling(DefaultBootstrap.java:224) 15:08:11.556 [stderr] at org.opensaml.DefaultBootstrap.initializeXMLTooling(DefaultBootstrap.java:207) 15:08:11.557 [stderr] at org.opensaml.DefaultBootstrap.bootstrap(DefaultBootstrap.java:100) 15:08:11.557 [stderr] at org.opensaml.PaosBootstrap.bootstrap(PaosBootstrap.java:27) 15:08:11.557 [stderr] at org.springframework.security.saml.SAMLBootstrap.postProcessBeanFactory(SAMLBootstrap.java:42) 15:08:11.557 [stderr] at org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors(PostProcessorRegistrationDelegate.java:284) 15:08:11.557 [stderr] at org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors(PostProcessorRegistrationDelegate.java:181) 15:08:11.557 [stderr] at org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors(AbstractApplicationContext.java:678) 15:08:11.557 [stderr] at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:520) 15:08:11.558 [stderr] at org.springframework.web.context.ContextLoader.configureAndRefreshWebApplicationContext(ContextLoader.java:444) 15:08:11.558 [stderr] at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:326) 15:08:11.558 [stderr] at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:107) 15:08:11.558 [stderr] at io.undertow.servlet.core.ApplicationListeners.contextInitialized(ApplicationListeners.java:187) 15:08:11.558 [stderr] at io.undertow.servlet.core.DeploymentManagerImpl.deploy(DeploymentManagerImpl.java:198) 15:08:11.558 [stderr] at org.wildfly.extension.undertow.deployment.UndertowDeploymentService.startContext(UndertowDeploymentService.java:100) 15:08:11.558 [stderr] at org.wildfly.extension.undertow.deployment.UndertowDeploymentService$1.run(UndertowDeploymentService.java:82) 15:08:11.559 [stderr] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) 15:08:11.559 [stderr] at java.util.concurrent.FutureTask.run(FutureTask.java:266) 15:08:11.559 [stderr] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) 15:08:11.559 [stderr] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) 15:08:11.559 [stderr] at java.lang.Thread.run(Thread.java:745) 15:08:11.559 [stderr] at org.jboss.threads.JBossThread.run(JBossThread.java:320) {code} For more information see: * https://issues.apache.org/jira/browse/XERCESJ-1667 * https://svn.apache.org/repos/asf/xerces/java/trunk/src/org/apache/xerces/... * https://github.com/jboss/xerces/pull/13
