How to fix NSInternalInconsistencyException in TornadoFX when running on macOS 10.14?

Question

I'm using TornadoFX and I've recently upgraded to macOS 10.14. The problem is that I get this error whenever I open a dialog and focus another application window:

libc++abi.dylib: terminating with uncaught exception of type NSException

There is a solution for this detailed in this question but my problem is that I'm using TornadoFX and I can't really tamper with its dependencies. What can I do to fix this?

This ticked suggests that this is fixed in u202 but I tried it and I can still reproduce this problem with u202 .

Answer 1

There is no relevant dependencies introduced by TornadoFX here, all you need is a version of Java 8 with the fix in place. As the release notes of u202 doesn't mention the fix for this issue, you should contact Oracle and ask them to clarify, and if there is a patch version available with the fix in place.
