[jboss-jira] [JBoss JIRA] (WFLY-6287) CXFHandlerResolverImpl not threadsafe

Bjørn Hilstad created WFLY-6287: ----------------------------------- Summary: CXFHandlerResolverImpl not threadsafe Key: WFLY-6287 URL: https://issues.jboss.org/browse/WFLY-6287 Project: WildFly Issue Type: Bug Components: Web Services Affects Versions: 9.0.1.Final Reporter: Bjørn Hilstad Assignee: Alessio Soldano When the concurrency of handler-chain parsing increases , the following error shows up in the logs: Caused by: org.xml.sax.SAXException: FWK005 parse may not be called while parsing. at org.apache.xerces.parsers.DOMParser.parse(DOMParser.java:260) at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(DocumentBuilderImpl.java:298) at javax.xml.parsers.DocumentBuilder.parse(DocumentBuilder.java:121) at org.jboss.wsf.stack.cxf.client.serviceref.CXFHandlerResolverImpl.createHandlerChain(CXFHandlerResolverImpl.java:161) ... 132 more One case where I have seen this is when an EJB/MDB uses @WebServiceRef and @HandlerChain to get a reference to a webservice. When multiple instances of the EJB/MDB are created at the same time to handle a lot of messages this happens. It is the @HandlerChain that triggers the xml parsing and gives the error. The Xerces DocumentBuilder is not threadsafe and thus requires code to synchronize it correctly. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
