Usage

From source file:com.bt.aloha.batchtest.PerformanceBatchTest.java

private void restartSimpleSipStack(int numberSimpleSipThreads) {
    ThreadPoolTaskExecutor threadPoolTaskExecutor = (ThreadPoolTaskExecutor) applicationContext
            .getBean("taskExecutor");
    threadPoolTaskExecutor.destroy();
    threadPoolTaskExecutor.setCorePoolSize(numberSimpleSipThreads);
    threadPoolTaskExecutor.initialize();
}

    // Extra tasks will be submitted before the termination is detected
    assertEquals(total, items.size() - frequency);
