When we run `jhsdb jstack --mixed` on Windows, we can see top of call frames only as following:
----------------- 4 ----------------- "main" #3 prio=5 tid=0x0000021ee0357e90 nid=22356 waiting on condition [0x0000004ae7eff000] java.lang.Thread.State: TIMED_WAITING (sleeping) JavaThread state: _thread_blocked 0x00007ffca3c41c44 ntdll!NtWaitForSingleObject + 0x14 ----------------- 5 ----------------- This is long standing bugs since JDK 9 at least (maybe this includes older JDK releases). We cannot depend on base pointer to unwind call frames, but SA do that. This PR use [GetStackTrace](https://learn.microsoft.com/en-us/windows-hardware/drivers/ddi/dbgeng/nf-dbgeng-idebugcontrol-getstacktrace) to find caller frame, then native call frames would be unwinded. However it has still problems for JIT'ed frames because it does not have a hint for unwinder like [RtlAddFunctionTable](https://learn.microsoft.com/en-us/windows/win32/api/winnt/nf-winnt-rtladdfunctiontable). But it would affect entire of JIT compilers, so I've limited the change to SA. This change passed serviceability/sa tests on Windows 11. ------------- Commit messages: - 8374469: Mixed jstack does not work on Windows Changes: https://git.openjdk.org/jdk/pull/29019/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=29019&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8374469 Stats: 138 lines in 6 files changed: 109 ins; 2 del; 27 mod Patch: https://git.openjdk.org/jdk/pull/29019.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/29019/head:pull/29019 PR: https://git.openjdk.org/jdk/pull/29019
