[jdk17u] RFR: 8277029: JMM GetDiagnosticXXXInfo APIs should verify output array sizes

Wed Nov 17 09:17:00 UTC 2021

Hi all,

this pull request contains a backport of commit b8d33a2a from the openjdk/jdk repository.

I'd like to backport this patch to jdk17 and jdk11. Most relevant this is for jdk11, to prevent difficult-to-spot downport errors early (the DCmd framework is different, which exposes authors of dcmd to surprising bugs - this downport helps prevent that).

Jdk17 downport mainly because it makes no sense to fix 11 and head and leave 17 as it is.

Thanks!
