I changed the Servlet3.Continuation.reset() method to this to 'fix' it:
{code:java} public void reset() {
if (!isResumed) {
context.complete();
}
obj = null;
}{code}
But I'm not sure if that's correct.
I also changed the Servlet3Continuation.startAsyncAgain() method, as I spotted
it adding a duplicate listener:
{code:java} void startAsyncAgain() {
AsyncContext old = context;
try {
context = req.startAsync();
context.addListener(this);
} catch (IllegalStateException ex) {
context = old;
}
}{code}
