This thinking was part of the logic behind JEP 449.

---> "Legacy systems are unlikely to migrate to versions of the JDK following the release of Java 21."

If there is a Java system still running on an old version of Windows 32-bit -- that will by the way soon be EOL -- it is unlikely that the team will move said system to a newer version of Java. More often than not, there are cases of users not even running the latest minor version of older major versions of Java (7, 8, 11).

Just curious if anyone has any visibility as to how widely 32-bit windows may still be in use?
I’d imagine there could still be a lot of older systems (and maybe some embedded case) with 32bit windows still in use which the removal risks some possible bad vibes for that user base.

Although I guess if they’re not updating to newer Windows (and hardware), they may not be upgrading Java without 32bit Windows support either.

Obviously the glory days of 32-bit support are over. But I'm guessing it
will be some more time before all 32-bit code can be dropped. So I think
it is important not to conflate dropping general 32-bit support with the
more specific case of dropping win32. The former is more about cpu
support, the latter more about os support.

Arm32 in specific has never had any really active backers; it seems to
be slowly dying but is apparently still on life-support. Let's keep that
out of the win32 discussion.
