unable to launch, java error

[Merlin-09]

Hello,
this is a great app, but I don't know why, after a reinstallation of gnome-ubuntu yakkety, I cannot launch it anymore. Here is the terminal output.

I believe it happened due to changes made in JDK 9. Something like mgarin/weblaf#452. Unfortunately, currently, I haven't access to my Linux laptop to test it and make pull request :(

[mgarin]

Yes, I can confirm that this is a WebLaF issue which appeared due to major internal changes made to the text antialias rendering within JDK 9. It basically happened because L&F developers were forced to access proprietary Sun API if they wanted to provide any kind of text rendering configurations at all.

Even though JDK 9 is not yet officially released (should be coming around July) and I do not generally recommend using it with WebLaF yet as there might be other various issues popping out - I will be pushing an update that will patch all currently known problems with it somewhere in the middle of the next week.

The only problem - those fixes will be going into WebLaF styling branch code and builds, but meow project (according to build file) uses older v1.28 version which will certainly not work on JDK 9 and later ones. So it is up to @pnmougel whether he will be updating the project or not.

In the meantime you can switch back to JDK 8 or earlier versions to avoid this issue, unless it is critical for your project to run under current JDK 9 ea builds.
