While researching <https://bugzilla.redhat.com/show_bug.cgi?id=1600551> it would noticed that networkaddress.cache.negative.ttl=10 in the Java s2i image.

I will share a message from the bugzilla that explains issue:

An aside: if any of these cases seem isolated to Java applications, please test setting the following JVM property in affected applications:

networkaddress.cache.negative.ttl=0

As documented at https://docs.oracle.com/javase/7/docs/technotes/guides/net/properties.html.

In a cloud environment, a negative lookup cache is problematic given the volatility of service names. In OpenShift specifically it's probably best to rely on the nameservers to manage DNS caching.
