  • ConcurrentModificationException while loading config

    we are getting the following exception when trying to load our config? We have a JUnit test class that does nothing except attempt to load the config. What could be causing this?

    Code:
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration("classpath:test-int-context.xml")
    public class TeshConfigLoad {
    
        @Test
        public void test() {
        	Date d = new Date(System.currentTimeMillis());
        	System.out.println("Test Completed at " + d);
        }
    }
    Code:

    By explicitly creating all channel names the issue has been resolved. Not really sure why the auto-creation of channels has caused this, but for now it is resolved. We will dig a little deeper to try to find out a cause.
