> The Lucene libraries supporting the Provenance Repository log the following
> messages related to experimental and native access settings at the JVM level.
> {noformat}
> INFO [Index Provenance Events-1] o.a.l.s.MemorySegmentIndexInputProvider
> Using MemorySegmentIndexInput and native madvise support with Java 21 or
> later; to disable start with
> -Dorg.apache.lucene.store.MMapDirectory.enableMemorySegments=false
> WARN [Index Provenance Events-1] o.a.l.i.v.VectorizationProvider Java vector
> incubator module is not readable. For optimal vector performance, pass
> '--add-modules jdk.incubator.vector' to enable Vector API.
> {noformat}
> These messages reflect parameters that should be changed for standard
> operation and can be confusing given the Lucene is an implementation detail
> of the Provenance Repository. For this reason, these log messages should be
> suppressed in the default Logback configuration
