Hi @Larry-N
Can you please justify why you want to backport this, especially to 17?
It seems a day zero issue, and I think it's rather an enhancement than a bug.
Also, can you please have a look at https://wiki.openjdk.org/display/JDKUpdates/How+to+contribute+or+backport+a+fix
and also revisit your other backports?
Thanks!

@GoeLin, The jtreg test com/sun/jdi/JdwpListenTest.java failing "ERROR: failed to attach" on linux-musl builds, for jdk21 and jdk17.
For the jdk24, the test passes smoothly.
It is both 8313804 and 8317804 that if applied together (since jdk23), solve the problem.
In jdk21 the 8317804 was already backported.
For jdk17 both of the fixes are absent.
