Could this be related to (closed) https://bugs.openjdk.java.net/browse/JDK-8179680? When searching the web for the error message, many projects seem to have this problem with JDK 9. In my case LanguaTool-4.0, too.
Another addition: this happens only on one of three attached screens. Logical screens 1 and 2 work, screen 3 (which is my primary screen) does not work.
Yet another addition: disabling screens 1 or 2 makes everything work on the remaining screens.
