lhotari opened a new pull request, #4586: URL: https://github.com/apache/bookkeeper/pull/4586
### Motivation Some tests fail due to DNS timeouts as explained in #4585. Some of these failures might be caused by the default negative DNS cache that is 10 seconds by default or by the default positive DNS cache that is 30 seconds by default. It's better to set reduce dns cache settings to 1 second for tests. ### Changes - pass `-Dsun.net.inetaddr.ttl=1 -Dsun.net.inetaddr.negative.ttl=1` in test JVM arguments to configure the DNS cache settings - For OpenJDK, it's not possible to override settings in `$JAVA_HOME/conf/security/java.security` with System properties, see https://github.com/openjdk/jdk11u/blob/master/src/java.base/share/classes/sun/net/InetAddressCachePolicy.java . By default there's a negative TTL setting set to 10 seconds. - apply respective settings to `$JAVA_HOME/conf/security/java.security` in CI -- This is an automated message from the Apache Git Service.
