> When an async request failed due to connexion timeout, callback is infinitly called.
> Exception thrown on connection error :
> javax.ws.rs.client.ClientException: javax.ws.rs.client.ClientException: java.net.ConnectException: Connection refused
> Analysis : In class HTTPConduit
> 1/ handleResponseOnWorkqueue:Runnable call handleResponseInternal();
> 2/ An exception is thrown because connexion timeout occurs
> 3/ Call back is called (method InvocationCallback:failed(ClientException error))
> 4/ No executor in method handleResponseOnWorkqueue is set so it execute a new runnable. =>I think it miss something to check if an exception was thrown
> I tried to :
> - cancel FutureTask in callback and in a different thread
> - Interrupt the current thread in the callback
> - Throw Runtime exception in order to break execution
> But it creates a new task before ending the execution.
> The only way I found to stop the loop was to patch : handleResponseOnWorkqueue and test if an exception was set before trying to execute something
> Stack trace of the loop :
