When you need to debug across the entire system and into the kernel, I'd use dtrace which has had java stack frame support since... I don't remember anymore, but closing in on 20 years.

No one uses dtrace anymore. bpftrace is integrated into the kernel and can extract btf type information embedded into the kernel binary.

Your (absurdly) broad claim is false -- and it's very easily disproven.[0]
