MOIRE Antony created CXF-6943: --------------------------------- Summary: Dead lock on Async Response when timeout is set Key: CXF-6943 URL: https://issues.apache.org/jira/browse/CXF-6943 Project: CXF Issue Type: Bug Components: JAX-RS Affects Versions: 3.1.6, 3.0.4 Environment: The bug was detected on : - Java 1.7.0_11 - Tomcat 8.0.23 - CXF 3.0.4 - Red Hat 6.5
The bug is also available on : - Java 1.8.0_77 - Tomcat 8.0.35 - CXF 3.1.6 - Red Hat 6.5 Reporter: MOIRE Antony Hello, When using AsyncResponse with timeout and an external thread for the treatment, it seems that a dead lock appears between the main http thread and the treatment thread when the treatment thread finished before the main thread : Here is the code which reproduces this issue : public Response asyncResponseTestKo(HttpServletRequest request, final AsyncResponse ar) { Response r = null; LOGGER.info("Get request asyncResponseTestKo"); ar.setTimeout(10, TimeUnit.SECONDS); poolExecutor.execute(new Runnable() { @Override public void run() { ar.resume(Response.ok().build()); } }); try { Thread.sleep(2000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } return r; } The main thread error is : 2016-06-15 14:47:44 "http-nio-9080-exec-1" -
