> Key: CXF-6609
> URL: https://issues.apache.org/jira/browse/CXF-6609
> Project: CXF
> Issue Type: Bug
> Components: Transports
> Affects Versions: 3.1.2
> Environment: windows jdk 1.8
> Reporter: Thomas Krieger
> Assignee: Sergey Beryozkin
> Priority: Minor
> Fix For: 3.1.3, 2.7.18, 3.0.7

> When using the demo.hw.server.HelloWorld client from different threads a data
> race occurs in org/apache/cxf/transport/http/HTTPConduit.prepare:
> if (this.authSupplier == null) {
> this.authSupplier =
> createAuthSupplier(effectiveAuthPolicy.getAuthorizationType());
> }
> I would suggest to make the field authSupplier volatile.
> Here is my Test client:
> public class TestCxfClient extends MultiThreadedOneInstanceTemplate {
>
> private static final QName SERVICE_NAME
> = new QName("http://server.hw.demo/";, "HelloWorld");
> private static final QName PORT_NAME
> = new QName("http://server.hw.demo/";, "HelloWorldPort");
> private final HelloWorld hw;
>
>
>
>
> public TestCxfClient(HelloWorld hw) {
> super();
> this.hw = hw;
> }
> public void exec()
> {
> System.out.println(hw.sayHi("World"));
>
>
> }
>
>
>
> public static void main(String[] args) throws Exception {
> Service service = Service.create(SERVICE_NAME);
> // Endpoint Address
> String endpointAddress =
> "http://localhost:8080/java_first_jaxws/services/hello_world";;
> // If web service deployed on Tomcat (either standalone or
> embedded)
> // as described in sample README, endpoint should be changed to:
> // String endpointAddress =
> "http://localhost:8080/java_first_jaxws/services/hello_world";;
> // Add a port to the Service
> service.addPort(PORT_NAME, SOAPBinding.SOAP11HTTP_BINDING,
> endpointAddress);
>
> HelloWorld hw = service.getPort(HelloWorld.class);
>
> (new TestCxfClient(hw)).test();
> }
> }
> public abstract class MultiThreadedOneInstanceTemplate implements Runnable {
> private final AtomicInteger threadCount = new AtomicInteger();
> public void test() throws Exception
> {
> for(int i = 0; i < 2 ;i++)
> {
> Thread thread = new Thread(this, "Thread " + i);
> this.threadCount.incrementAndGet();
> thread.start();
> }
> while( this.threadCount.get() > 0 )
> {
> Thread.sleep(1000);
> }
> Thread.sleep(10 * 1000);
> }
> public void run()
> {
> exec();
> threadCount.decrementAndGet();
> }
> protected abstract void exec();
> }
