Hello,

With the preamble of my opinion not being an authoritative point of view at all, I should point out that Java/JVM based services are not especially loved in WMF. Ops does not feel it has the capability of supporting them. There are a few around like Gerrit, Cassandra, ElasticSearch, Kafka but none of these is actually maintained by ops. All of these have owners/maintainers outside of ops (entire teams in some cases), with varying degrees of success. The question of whether it should be Tomcat or Jetty, is a valid one, but serves to alleviate only part of the problem (it's not like Ops hate tomcat but like Jetty). So, there are probably a few social/administrative issues that it might make sense to address first before handling the technical part.

I think what you means is : if the service is online,for administration , a maintainer or a team is needed just like Gerrit,Cassandra, and ElasticSearch did. Not maintained by the OPs. The team need to be set first. Am I right?

Yes, that's the very least IMHO.
