Use byte-buddy classes optimized for Java8+ - #8735

mcculls · 2025-04-25T09:56:28Z

What Does This Do

byte-buddy now ships classes optimized for Java8+ under META-INF/versions/9

since we target Java8+ we can promote these classes over the pre-Java8 ones

Motivation

these classes should allow for faster class file validation and CDS support on JDK 8 and later
