[infinispan-issues] [JBoss JIRA] (ISPN-2955) Async marshalling executor retry when queue fills

Async marshalling executor retry when queue fills ------------------------------------------------- Key: ISPN-2955 URL: https://issues.jboss.org/browse/ISPN-2955 Project: Infinispan Issue Type: Enhancement Components: Marshalling Affects Versions: 5.2.5.Final Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 5.3.0.Beta1, 5.3.0.Final When using an async transport and async marshalling, an executor is used to process the marshalling task in a separate thread and the caller's thread is allowed to return immediately. When the executor's queue fills and the queue cannot accept any more tasks, it throws a {{RejectedExecutionException}}, causing a very bad user/developer experience. A more correct approach to this is to catch the {{RejectedExecutionException}}, block and retry the task submission. The end result is that, in the degenerate case (when the executor queue is full) instead of throwing exceptions, those invocations will perform slightly slower.
