Sets the maximum amount of time (in milliseconds) the #borrowObject method should block before throwing an exception when the pool is exhausted and the #setWhenExhaustedAction "when exhausted" action is #WHEN_EXHAUSTED_BLOCK .

Usage

From source file:edu.illinois.enforcemop.examples.apache.pool.TestGenericKeyedObjectPool.java

public void testBlockedKeyDoesNotBlockPool() throws Exception {
    SimpleFactory factory = new SimpleFactory();
    GenericKeyedObjectPool pool = new GenericKeyedObjectPool(factory);
    pool.setWhenExhaustedAction(GenericObjectPool.WHEN_EXHAUSTED_BLOCK);
    pool.setMaxWait(5000);
    pool.setMaxActive(1);/* w  w w .  j  av  a 2s .com*/
    pool.setMaxTotal(-1);
    pool.borrowObject("one");
    long start = System.currentTimeMillis();
    // Needs to be in a separate thread as this will block
    Runnable simple = new SimpleTestThread(pool, "one");
    Thread borrowThread = new Thread(simple, "borrowThread");
    borrowThread.start();
    // This should be almost instant. If it isn't it means this thread got
    // stuck behind the thread created above which is bad.
    // Give other thread a chance to start        
    //Thread.sleep(1000);    
    pool.borrowObject("two");
    long end = System.currentTimeMillis();
    // If it fails it will be more than 4000ms (5000 less the 1000 sleep)
    // If it passes it should be almost instant
    // Use 3000ms as the threshold - should avoid timing issues on most
    // (all? platforms)
    //assertTrue ((end-start) < 4000);
