 throw new ClientAbortException(e);  // it will handled by
 outter code.But now the commit equals true when sendError method execute,
 so
//IllegalStateException will throw.
 }
 }
 
 Does the response will set commit = true when the client close or abort?

No.

 In source code, I just find the flush method or close method will set
 commit = true, others was correct request/response lifecycle.
 
 Thanks in advance.
