> Derby can't be built with JDK 9. Java 9 introduces new JDBC classes like java.sql.ShardingKey
and methods which refer to these new classes.
> In addition, project Jigsaw has created a new way to name classes (see http://openjdk.java.net/jeps/220).
This breaks the PropertySetter build tool which we use so that old JVMs can compile Derby
and so that Derby can be compiled to run on old JVMs.
> It is likely that we will need to leave this issue open throughout the development cycle
of Java 9.
