You're are (or were) right. Java has (had) an awful performance of a foreign API call, and I wonder was this fixed in this release, because as I heard, fixing it was the main reason of the upcoming functionality

It could bring Java closer in FFI overhead but not necessarily match. There are still missing features like structs, C pointers (though in C# they are superseded quite a bit by byrefs aka `ref T` syntax, e.g. used by Span<T>), stack allocated buffers, etc.

C# also has function pointers (managed/unmanaged) and C exports with NativeAOT.
