             Summary: LastModifiedTime not updated for Destroy/Remove
                 Key: GEODE-7764
                 URL: https://issues.apache.org/jira/browse/GEODE-7764
             Project: Geode
          Issue Type: Bug
          Components: regions, statistics
            Reporter: Juan Ramos


This issue was raised through [this|https://stackoverflow.com/questions/54764977/why-is-lastmodifiedtime-in-distributedregionmxbean-is-not-updated-if-data-is-del] StackOverflow question, basically the `lastModifiedTime` is not updated after a `destroy`/`remove` operation.
The following test can be used to consistently reproduce the issue:

{code}
@Category(OQLQueryTest.class)
@RunWith(JUnitParamsRunner.class)
public class StackOverflowTests {
  private static final String REGION_NAME = "testRegion";

  @Rule
  public ServerStarterRule server = new ServerStarterRule().withJMXManager().withAutoStart();

  private Region<String, String> setUpRegion(RegionShortcut regionShortcut) {
    return server.getCache().<String, String>createRegionFactory(regionShortcut)
        .setStatisticsEnabled(true)
        .create(REGION_NAME);
  }

  @Test
  @Parameters({"REPLICATE", "PARTITION"})
  public void lastModifiedTimeForRemove(RegionShortcut regionShortcut) {
    Region<String, String> region = setUpRegion(regionShortcut);
    long initialLastModifiedTime = region.getStatistics().getLastModifiedTime();

    region.put("key1", "value1");
    await()
        .atMost(1, TimeUnit.MINUTES)
        .untilAsserted(() -> assertThat(region.getStatistics().getLastModifiedTime()).isGreaterThan(initialLastModifiedTime));
    long lLastModifiedTimeAfterPut = region.getStatistics().getLastModifiedTime();

    region.remove("key1");
    await()
        .atMost(1, TimeUnit.MINUTES)
        .untilAsserted(() -> assertThat(region.getStatistics().getLastModifiedTime()).isGreaterThan(lLastModifiedTimeAfterPut));
  }

  @Test
  @Parameters({"REPLICATE", "PARTITION"})
  public void lastModifiedTimeForDestroy(RegionShortcut regionShortcut) {
    Region<String, String> region = setUpRegion(regionShortcut);
    long initialLastModifiedTime = region.getStatistics().getLastModifiedTime();

    region.put("key1", "value1");
    await()
        .atMost(1, TimeUnit.MINUTES)
        .untilAsserted(() -> assertThat(region.getStatistics().getLastModifiedTime()).isGreaterThan(initialLastModifiedTime));
    long lLastModifiedTimeAfterPut = region.getStatistics().getLastModifiedTime();

    region.destroy("key1");
    await()
        .atMost(1, TimeUnit.MINUTES)
        .untilAsserted(() -> assertThat(region.getStatistics().getLastModifiedTime()).isGreaterThan(lLastModifiedTimeAfterPut));
  }
}
{code}
