Implement EventsByTag in javadsl.PersistenceTestKitReadJournal.scala

Hi

I wanted to Query events by tag using EventsByTag with org.apache.pekko.persistence.testkit.query.javadsl.PersistenceTestKitReadJournal. Unfortunately this interface is not implemented yet. The scala-Version does implement EventsByTag. Is there a specific reason for this? As far as I can tell (I'm no Scala-Developer) one could simply add an additional delegate method.

I also saw that the org.apache.pekko.persistence.testkit.query.scaladsl.PersistenceTestKitReadJournal does not support specifying an offset other than NoOffset. This will probably be my next issue...

What I actually want to do is to replace io.github.alstanchev.pekko.persistence.inmemory.query.javadsl.InMemoryReadJournal with something that is included in the "standard" pekko libs. Is there another option? I saw that there is a org.apache.pekko.persistence.journal.inmem.InmemJournal but I could not figure out how I'm supposed to use that. How would I configure that in application.conf?

Thanks and regards
Oliver
