RFR: 8375016: Several catch blocks for NullPointerExceptions exist in the codebase

Mon Jan 12 14:19:42 UTC 2026

This PR replaces various catch blocks for NPEs by proper null checks. It looks like a lot but most of the binding changes are just variants of the same approach. The test cases have been adapted to not check for NPEs anymore.

The PrismFontFactory change to a RuntimeException was made because I don't see how the try block can throw an NPE.
