Todd Ciezadlo updated ISPN-1213:
--------------------------------

    Steps to Reproduce:   (was: package org.infinispan.api.tree;

import org.infinispan.Cache;
import org.infinispan.config.Configuration;
import org.infinispan.manager.EmbeddedCacheManager;
import org.infinispan.test.SingleCacheManagerTest;
import org.infinispan.test.fwk.TestCacheManagerFactory;
import org.infinispan.tree.TreeCache;
import org.infinispan.tree.TreeCacheImpl;
import org.infinispan.util.logging.Log;
import org.infinispan.util.logging.LogFactory;
import org.testng.annotations.Test;

import static org.testng.AssertJUnit.assertEquals;

@Test(groups = "functional", testName = "api.tree.ExpirationTest")
public class ExpirationTest extends SingleCacheManagerTest {
    private Log log = LogFactory.getLog(ExpirationTest.class);
    private TreeCache<String, String> cache;

    @Override
    protected EmbeddedCacheManager createCacheManager() throws Exception {
       // start a single cache instance
       Configuration c = new Configuration();
       c.setInvocationBatchingEnabled(true);
       c.setExpirationMaxIdle(5000);

       EmbeddedCacheManager cm = TestCacheManagerFactory.createCacheManager(c, true);

       Cache flatcache = cm.getCache();
       cache = new TreeCacheImpl(flatcache);

       return cm;
    }

    public void testDanglingChild() throws Exception {
        String testFqn = "TEST_FQN";
        String testKey = "TEST_KEY";
        String testValue = "TEST_VALUE";

        cache.put(testFqn, testKey, testValue);
        assertEquals(testValue, cache.get(testFqn, testKey));

        log.info("Sleeping for 3000 ms");
        Thread.sleep(3000);

        // Touch the child before the max-idle is reached.
        assertEquals(testValue, cache.get(testFqn, testKey));

        log.info("Sleeping for 3000 ms");
        Thread.sleep(3000);

        assertEquals(testValue, cache.get(testFqn, testKey));

        // The root should not expire because its child was touched.
        assertEquals(1, cache.getRoot().getChildren().size());
    }
}
)

> TreeCache parents expire according to the max-idle value even if they contain children.  This puts the tree cache in an inconsistent state since the "dangling" children can be retrieved through TreeCache.get(FQN, String) calls, but cannot be traversed to through TreeCache.getRoot() and Node.getChildren() calls.
> Copied a unit test to Steps to Reproduce.
