Kevin Risden commented on SOLR-9515:
------------------------------------
So I see three ways forward short term - none of which I really like.
# Disable Hadoop tests on JDK9+
## Part of this Hadoop 3 upgrade was to make it possible to run on JDK9+
potentially with Hadoop support.
## There are other Hadoop tests currently disabled with JDK9+ due to existing
issues.
# Copy and patch BlockPoolSlice to change how the ForkJoinPool is created
## BlockPoolSlice looks to be the only place where ForkJoinPool will cause
issues for the tests. I am currently validating this.
## We would end up with 2 classes copied to make the Hadoop integration tests
work.
# Don't upgrade to Hadoop 3 until Hadoop is more SecurityManager friendly.
Long term it would be good to fix Hadoop to make it more SecurityManager
friendly.
