Review comment:
       I think we need to add 
   
`ProblemFilters.exclude[DirectMissingMethodProblem("org.apache.spark.api.java.JavaRDDLike.treeAggregate")`
   
`ProblemFilters.exclude[DirectMissingMethodProblem]("org.apache.spark.rdd.RDD.treeAggregate")`

Review comment:
       nit: already the default value is `false` right?
