This looks suspiciously like:
  https://bugs.openjdk.java.net/browse/JDK-8210457

That fix is already backported to 11.0.4.

Further diagnostics can be helped with running with fastdebug build, and running on latest JDK too.
You can have the binaries here:
  https://builds.shipilev.net/openjdk-jdk11-dev/ (bleeding edge 11.0.4+)
  https://builds.shipilev.net/openjdk-jdk/       (bleeding edge 13+)
