> URL: https://issues.apache.org/jira/browse/CXF-6940
> Project: CXF
> Issue Type: Bug
> Components: JAX-WS Runtime
> Affects Versions: 3.1.4
> Environment: IBM JDK 1.7, Apache CXF installed as resource Adapter on
> IBM WebSphere 8.5.5.3 on RHEL 6.0
> Reporter: Dhawalpatel
> Assignee: Daniel Kulp
> Priority: Critical
> Fix For: Invalid

> Hi Daniel,
> Test Scenario:
> Install CXF as Resource Adapter in J2EE Container and use below code to call
> a JAX-WS API.
> /* Lookup Resource Adapter of JCA and get COnnection*/
> CXFConnectionFactory connectionFactory = getCXFConnectionFactory(portClass);
> CXFConnectionSpec connectionSpec = createCXFConnectionSpec(portClass,
> serviceName, portName, webServiceDefinition);
> /* Get the Port from JCA Connection pool*/
> connection = connectionFactory.getConnection(connectionSpec);
> port = connection.getService(portClass);
> /* Close the JCA Connection*/
> if(connection != null)
> connection.close();
> /*WebService call*/
> port.getAccount();
> Description:
> When a JCA Connection pool eviction happens due to Max Connections reached
> state, the existing on-going outgoing JAX-WS Calls errors out with below
> exception:
> Message received on a Client that has been closed or destroyed.

> On further investigation, it seems you changed the code in ClientImpl.java as
> per https://issues.apache.org/jira/browse/CXF-3765 and change log
> https://fisheye6.atlassian.com/changelog/cxf?cs=e0ef66391d2e7e62e63e96214eca95e292271892
> by adding the additional cleanup code in ClientImpl.java the below lines
> bus = null;
> conduitSelector = null;
> outFaultObserver = null;
> outboundChainCache = null;
> inboundChainCache = null;
> currentRequestContext = null;
> requestContext.clear();
> requestContext = null;
> responseContext.clear();
> responseContext = null;
> executor = null;
> The above lines added by you for cleanup has broken the behavior of using the
> JCA connection for getting port and closing it immediately and then using the
> port to call the webservice. This leads to above exception when JCA Pool
> maxes out causing an eviction on JCA Pool by below thread stack causing the
> ClientImpl's destroy to be called and ultimately the bus obj ref getting set
> to null by your code and ultimately this exception.
> The behavior in CXF 2.3 was perfectly fine with no such problems. This was
> introduced by above mentioned code fix.

> Please fix this behavior since its not in the alignment to the behavior
> mentioned in JCA Spec and as per the documentation provided in CXF as well.
> Thanks
