@lukehutch The latest version in Maven is still 4.8.34. I will test after it is updated to 4.8.35 in Maven.

@ahamana You’re right, there was a transient failure on Sonatype. I just pushed the release again. You should be able to get the jar from Sonatype now, or it usually takes an hour or two to sync to Maven Central.
