Right, and I think this problem is isomporphic to the problem we have in Linux distros of selecting between libclang.so.1 and libclang.so.2. `System::loadLibrary` cannot do it. So, I think it would feel odd if, say AIX was able to load precise version of a library using the member syntax, but in all other platforms that would not be possible. For better or worse, the story for now is: if you want version, use `System::load`. In this case, the problem might be that `System::load` doesn't work out of the box, as the path doesn't really exist. But this doesn't seem different to loading non-existing framework paths in MacOS - e.g. it is a special case that can be added for AIX (when using `System::load`). All that said, if one is doing `System::load/loadLibrary` just because they want to use FFM and `Linker`, a better way to do that is to just use `SymbolLookup::libraryLookup` directly, which gives you direct access to whatever string `dlopen` accepts in your system. Now, I realize that `jextract` is currently using `SymbolLookup::loaderLookup`, but I believe we can change that, which in turn will make adding support for AIX a bit easier. ------------- PR Comment: https://git.openjdk.org/jdk/pull/17945#issuecomment-2015299960
