@mwullink

Description

@mwullink

The test below crashes Java 11 runtime, when the line that adds the DNSSEC extension is removed then the test runs fine.

with this line the java vm crashes, without it runs fine.
extensions.put(ExtensionName.DNSSEC_RETURN_STATUS, GetDNSConstants.GETDNS_EXTENSION_TRUE);

  @Test
  public void testdnssecTemp() {
    String queryString = "getdnsapi.net";
    String type = "A";
    final IGetDNSContextSync context = GetDNSFactory.createSync(1, null);
    HashMap<ExtensionName, Object> extensions = new HashMap<ExtensionName, Object>();
    extensions.put(ExtensionName.DNSSEC_RETURN_STATUS, GetDNSConstants.GETDNS_EXTENSION_TRUE);

    HashMap<String, Object> info =
        context.generalSync(queryString, RRType.valueOf(type), extensions);

    if (info != null) {
      System.out.println(info);
    } else {
      System.out.println("No response form DNS SERVER");
    }

    context.close();

  }
