* `org.db4j : kilim : 2.0.1` supports java 8, 9, and 11

* openjdk 10 has a bug and refuses to load certain valid classfiles that use lambdas. see the readme for workarounds if you must use java 10

recent improvements:

- added a fork-join scheduler and made it much easier to add custom schedulers
