    copied!<p>I Have REST service</p> <pre><code>@Path("/rest") @Component public class MyRestService { @Inject private MyBean bean; @GET @Path("/do") public String start() { this.logger.info("Before do " + Thread.currentThread().getId()); String result = this.bean.do(); this.logger.info("After do " + Thread.currentThread().getId()); return result; } } </code></pre> <p>which calls method of injected Spring singleton bean (with some state inside)</p> <pre><code>@Service public class MyBean { public String do() { // do something big... } } </code></pre> <p>When I call ".../rest/do" in browser the first call goes as expected, but if I make same call in another tab this call waits until first is finished to process second call in same thread.</p> <p>If I do second call as ".../rest/do?async=true" it does not wait and processes second request in new thread, but if I do both requests as ".../rest/do?async=true" - second one again waits for the first one to finish.</p> <p>What could be the reason for such behavior?
