Exception is simply true.
Useless without further description.

Please reopen. Here's some more:

public class JDK9Test
{
    public static void main(String[] args) throws IOException
    {
        ImageIO.getImageReadersByFormatName("JBIG2").next();
    }
}

run this on JDK9 early access (you can build on a lower system), and this is the stack trace you'll get:

Travis CI does not yet support Java 9. The test will be done manually beside the usual CI. I opened a follow-up issue - see #17.

Sorry for posting here. I've not yet found this error elsewhere in the web. @THausherr or @krzikams did you found a solution for this problem on JDK9? We get this when we add geotools to our dependencies, see here: https://travis-ci.org/graphhopper/graphhopper/jobs/176670700

We've managed to setup a travis build which fetches JDK9 (maybe interesting for your #17), see here: graphhopper/graphhopper#806

Sorry, it looks like you fixed your problem with #18, will see how we can use this information.
