There are at least two Java bytecode compilers. Though javac is obviously the "reference", there is also egc. It's used primarily by IDEs and editor plugins (like Eclipse, from whence it came, and the RedHat Java plugin for VS Code). Still, if memory serves there have been a handful of cases where egc's implementation of the spec differed from javac's with resulting fixes in javac itself (though I don't have sources at hand, so perhaps I misremember).
