It is original code in the JDK library. zlib is copied in from elsewhere. That is what I mean by third party code.

The only reason hsdis is specially treated is due to the fact that the original implementation was based on binutils, which could not -- for legal reason -- be distributed as a compiled library alongside the JDK. That forced us to erect an artificial barrier.

There are multiple JBS issues trying to rectify this, with different approaches, to get a non-binutils hsdis library build and shipped as any other native library in the JDK.
