Examples of org.apache.commons.pool2.PoolUtils$ErodingPerKeyKeyedObjectPool

org.apache.commons.pool2.impl.AbandonedConfig
Extends ErodingKeyedObjectPool to allow erosion to take place on a per-key basis. Timing of erosion events is tracked separately for separate keyed pools.

        SimpleTestThread<Waiter> t2 = new SimpleTestThread<Waiter>(waiterPool, "51");
        Thread thread2 = new Thread(t2);
        thread2.start();  // Triggers clearOldest, killing all of the 0's and the 2 oldest 1's
        Thread.sleep(50); // Wait for clearOldest to kick off, but not long enough to reach the 1's
        Waiter waiter = waiterPool.borrowObject("1");
        Thread.sleep(200); // Wait for execution to happen
        waiterPool.returnObject("1", waiter);  // Will throw IllegalStateException if dead
        waiterPool.close();
