Hi Alexey,
I've checkout the trunk, recompile, and re-run my test case.
Everything now run fine with 1.9.29-SNAPSHOT ! Many thanks !
I'll do some others tests tomorrow and if ok try to integrate it in our real server.
BTW: do you know when you will release the 1.9.29 ?
Again, thanks you very much.
Regards, David.

Hi all,
I've got a problem with Grizzly with the Suspend/Resume mode.
I've write a small test trying to reproduce what's happen sometimes in our server.
(A whole Maven project is attached, just unzip and run 'mvn clean test' to reproduce it)
Basically this test suspend the response and delegate the computation of the request to a Thread pool executor and then resume the request.
While running the test, there are some error, most often there is a NPE here :
java.lang.NullPointerException
at com.sun.grizzly.tcp.Response.resume(Response.java:784)
at com.acme.MyExecutor.run(MyExecutor.java:55)
at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886)
at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)
at java.lang.Thread.run(Thread.java:619)
(I made the test on windows XP with JDK 1.6.0_21)
I would like to know if someone has already see this problem ?
Is what I am doing just crazy ? ;-)
Do I misunderstand how to play with suspend/resume ?
Is there a problem in Grizzly ?
PS1 : I have better result if I add a small sleep here in the MyExecutor class :
...
@Override
public void run()
{
try
{
Thread.sleep( 5 );
res.setStatus( 200 );
...
It sounds like a synchronize problem ?
PS2 : I also made the test on an Ubuntu, and I've other problems :
GRAVE: GRIZZLY0038: HTTP Processing error.
