Kestrel 2.9.2 doesn't initialize properly in Java about kestrel

[eric]

You can use Option.apply(the_thing) to instantiate an Option.

Also, if you want to fix the problem of seeing %s in the logs, this can help:

Eric, Thanks a ton for the tip of Option.apply(), it worked. Provided all 14 arguments and could start the queue.

I don't understand why %s shows up. Is it due to bad logger configuration?
BTW found that jul-over-slf4j has horrible performance, it is 60 times slower. Please see here http://www.slf4j.org/legacy.html

Thanks again !

Posting java code which worked for me:

    Duration oneSecond = new Duration(1000000000);  // 1sec
    Duration forever = Duration.forever() ;
    QueueConfig qc = new QueueConfig(50000, new StorageUnit(1024*1024*50), new StorageUnit(1024*1024*10), 
            Option.apply(forever), /* defaultJournalSize*/ new StorageUnit(1024*1024*50), /* maxMemorySize */new StorageUnit(1024*1024), 
            /* maxJournalSize */ new StorageUnit(1024*1024*50), false, true, 
            oneSecond, Option.apply("None"), /* doesn't matter as expireQueue is false */ 1, false, Option.apply(forever));
    System.out.println("config: " + qc.toString());
    // creating timer and service
    java.util.concurrent.ScheduledExecutorService service = java.util.concurrent.Executors.newSingleThreadScheduledExecutor();
    Timer timer = new JavaTimer();
    PersistentQueue queue = new PersistentQueue("test", "./kestreltmp", config, timer, service);
    queue.setup();

    // finally
    queue.close();
    timer.stop(); // else JVM will wait on this thread.

For the expireToQueue setting, you may want to use Option.empty() instead of Option.apply("None") to represent nothing.
