Steps to Reproduce

I'm trying to set this up for simple and quick experimentation, so no gradle or maven (otherwise I'd just use an IDE) and it works well for just the base JDK, but I'm having trouble with adding in JavaFX. According to the "Troubleshooting" section I can add jar file dependencies as in my above config, but jdtls isn't finding the classes despite that config (I've restarted it as well). The jar files are the standard jars from the openjfx sdk (using SDK 17 to match the JDK). Edit: log only shows "The language server jdtls triggers a registerCapability handler despite dynamicRegistration set to false. Report upstream, this warning is harmless".

Expected Result

Dependencies are added and "searchable" with jdtls. Edit: this issue indicates that it should work this way with JavaFX.

Actual Result

Still only finds the regular JDK classes, not the JavaFX classes.
