This is a known bug in the latest release of High Sierra. There is supposedly a workaround by installing the Apple legacy Java 6 runtime (https://support.apple.com/kb/DL1572). We're reporting the issue to Apple, and it's affecting most java-based apps on the mac, so I expect it'll probably be resolved in the next beta update. It seems to occur when the operating system language is set to something other than English. Can you confirm if this is the case with your system?
