Tadayoshi Sato created JBWS-3847: ------------------------------------ Summary: Memory leak in JBoss WS CXF Client's HandlerChainSortInterceptor Key: JBWS-3847 URL: https://issues.jboss.org/browse/JBWS-3847 Project: JBoss Web Services Issue Type: Bug Components: jbossws-cxf Affects Versions: jbossws-cxf-4.3 Reporter: Tadayoshi Sato {{HandlerChainSortInterceptor.handleMessage(Message)}} sorts and sets JAX-WS handlers every time it handles a SOAP message: {code:java} public void handleMessage(Message message) throws Fault { if (binding != null) { @SuppressWarnings("rawtypes") List<Handler> list = binding.getHandlerChain(); if (list != null && !list.isEmpty()) { Collections.sort(list, comparator); binding.setHandlerChain(list); } } } {code} However, inside the {{org.apache.cxf.jaxws.binding.AbstractBindingImpl}} and {{org.apache.cxf.jaxws.support.JaxWsEndpointImpl}} implementations the handler chain is not reset every time but piled up with interceptors, which leads to subtle but indefinite memory leak in JBoss WS CXF client. Furthermore, {{org.apache.cxf.jaxws.support.JaxWsEndpointImpl}} holds the interceptors as a kind of {{java.util.concurrent.CopyOnWriteArrayList}}. So modifying the growing list of interceptors per each message should cause a growing performance drawback, which is also not a good implementation. -- This message was sent by Atlassian JIRA (v6.3.1#6329)
