Description

With thanks to @unknownhad for bringing this to our attention, there are a few places where we allow a short to become an int with sign extension, resulting in a negative value. We need to use Short.toUnsignedInt() consistently.

Research direction

Start by searching the spring-boot-loader sources for places where short values are converted to int, then inspect the surrounding handling for sign extension. Replace the inconsistent conversions with unsigned handling and verify that all affected values remain non-negative, using the loader's existing tests if available.
