             Summary: Using non-blocking thread pool causes excessive RejectedExecutionExceptions to be logged
                 Key: JBWEB-276
                 URL: https://issues.jboss.org/browse/JBWEB-276
             Project: JBoss Web
          Issue Type: Enhancement
      Security Level: Public (Everyone can see)
    Affects Versions: JBossWeb-7.2.0.Beta1
            Reporter: James Livingston
            Assignee: Remy Maucherat


When a finite-queue thread pool is used to process web requests, the queue being full can either block or drop the request. If you use a pool which drops requests, a RejectedExecutionException is thrown.

Currently JIoEndpoint catches that exception the same as other ones such as being unable to create threads. When using a non-blocking pool, the task being rejected is not a critical error like other exceptions so should not be logged at ERROR level.


Under excessive load, these exception will be continuously generated as requests are dropped, which cases a large amount of logging. Setting it to DEBUG level would stop that, but it would hide the potentially useful messages by default.
