java - jetty hangs on when accessing ServletRequest methods in async context -

i running code given in answer question-

servlet-3 async context, how asynchronous writes?

instead of response.getwriter().write(some_big_data); i've changed line

 servletrequest req= ctx.getrequest();   response.getwriter().write(req.getcontenttype()); 

now, request timing out. how can access request object?

i'm assuming having problems using code snippet within own thread after startasync() call.

per servlet 3.0 spec, section 2.3.3.4, access request , response objects not thread-safe. in fact, depending on state of object lifecycle, request , response objects can recycled.

it encouraged grab need request , response objects before startasync() , use references own thread.

in other words, use of ctx.getrequest() , response.getwriter() should done before startasync()
