- spark4 profile (-Dspark=4): Spark 4.2.0, Scala 2.13.18, Java 17, graphframes-spark4_2.13 0.12.3. Graphframes artifact is now a property so spark-3.5 keeps graphframes-spark3_2.12.
- Scala 2.13 compile fixes that also work on 2.12: HasStopWords uses java.io.Serializable, SparkFrame passes immutable lists, SparkBlockFunction uses JavaConverters, TestUDFDoubleWrappedArr drops WrappedArray.
- -usejavacp for scala-maven-plugin in spark/client.
- jacoco 0.8.12 so coverage reports can read Java 17 class files.
