> This patch changes all VaList implementations to throw `NoSuchElementException` when out of bounds reads occur on a VaList that is created using the Java builder API. The docs are updated accordingly.
> 
> For VaLists that are created from native addresses, we don't know their bounds, so we can not throw exceptions in that case.
> 
> Testing: `jdk_foreign` test suite on all platforms that implement VaList.
