What's wrong with using the standard JDK for Java code?

Nothing wrong with it. Why would you assume the author is in anyway hinting that there's something wrong with using the standard JDK for Java code?

Ok. Let me ask differently. Why would I download and use LLVM for working with java code? Which usecases favor this?

It's more an fun educational overview of the new FFM API.

I can't think of many actual use-cases where you'd want to use the LLVM JIT over those built-in to HotSpot.

Interfacing with existing LLVM-based systems, writing a very tight inner loop using LLVM where you absolutely need LLVM-like performance, or creating a compiler that targets LLVM using Java would be the main "real-world" use-cases.
