Description

Following the changes introduced in https://github.com/apache/geode/pull/4629, hangs are frequently observed when starting more than one server configured with an async-distribution-timeout when running on JDK 11.

A test to reproduce the issue is provided below:

public class ConnectionChangeHangTest {
  int serversToStart = 3;

  @Rule
  public ClusterStartupRule cluster = new ClusterStartupRule(serversToStart + 1);

  @Test
  /*
   * This test must be run with JDK 11 for it to show the hang
   */
  public void test() {
    MemberVM locator = cluster.startLocatorVM(0);
    int locatorPort = locator.getPort();

    for (int i = 0; i < serversToStart; ++i) {
      cluster.startServerVM(i + 1, s -> s.withConnectionToLocator(locatorPort)
          .withProperty("async-distribution-timeout", "5"));
    }
  }
}
