After updating the JDK, we end up with some native loading issues that cause erroneous syntax highlighting. Sketches run fine, but the pre-processor needs to be looked at.

@catilac . I'll take a look into this issue

Just looked into this, Terumin-jdk 25 no longer includes the jmod files that the pre-processor uses to know what is included in the java standard library. That's why we are seeing these underlines.
