Hi,
I downloaded an early access version of Java 9 from
http://download.java.net/java/jdk9/archive/116/binaries/jre-9-ea+116_windows-x64_bin.exe
and tried to start OpenJUMP with it. OJ did not start. With core the error was
Caused by: java.lang.NumberFormatException: For input string: ""

By reading
https://jaxenter.com/how-java-9-and-project-jigsaw-may-break-your-code-116965.html
I wonder if it is com.sun.media.imageio that breaks the code and how difficult
it would be to make OpenJUMP to run with Java 9. Perhaps that would become
OpenJUMP 2 because probably it would not be backwards compatible.
I made a very short test with JTS 1.14 and testbuilder seems to work with jre-9.
