Documentation in the XSD for the queue-length is incorrect based on the model description ----------------------------------------------------------------------------------------- Key: WFLY-8516 URL: https://issues.jboss.org/browse/WFLY-8516 Project: WildFly Issue Type: Bug Components: EE Reporter: James Perkins Assignee: James Perkins Labels: concurrency The documentation for in the XSD for the {{queue-length}} on the {{managed-executor-service}} states: {quote} A managed executor service (implementing javax.enterprise.concurrent.ManagedExecutorService). If the "thread-factory" attribute is not defined a managed thread factory with no context service and normal thread priority will be created and used by the executor. The task queue is based on the values of "core-threads" and "queue-length": * If "queue-length" is 0, or "queue-length" is Integer.MAX_VALUE (2147483647) and "core-threads" is 0, direct handoff queuing strategy will be used and a SynchronousQueue will be created. * If "queue-length" is Integer.MAX_VALUE but "core-threads" is not 0, an unbounded queue will be used. * For any other valid value for "queue-length", a bounded queue wil be created. {quote} The model description states: {quote} The executors task queue capacity. A length of 0 means direct hand-off and possible rejection will occur. An undefined length (the default), or Integer.MAX_VALUE, indicates that an unbounded queue should be used. All other values specify an exact queue size. If an unbounded queue or direct hand-off is used, a core-threads value greater than zero is required. {quote} The two descriptions should match. The model validation should also be checked as one of the messages doesn't seem to be correct: {code:java} // Validate an unbounded queue if (!queueLength.isDefined() || queueLength.asInt() == Integer.MAX_VALUE) { if (coreThreads.isDefined() && coreThreads.asInt() <= 0) { throw EeLogger.ROOT_LOGGER.invalidCoreThreadsSize(coreThreads.asString()); } } {code} That message doesn't really describe the real problem and will always be {quote} WFLYEE0112: The core-threads value must be greater than 0 when the queue-length is 0 {quote}
