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 :
