Description
HDFS-13768 introduced ForkJoinPool to improve performance of BlockPoolSlice. The created ForkJoinPool doesn't pass in a custom thread factory and by default the thread factory prevents all privileges under the Java SecurityManager.
This broke when integrating Hadoop 3.2.0 with Apache Solr in SOLR-9515.
It isn't clear that the ForkJoinPool is necessary when a regular normal executor could work instead?
