Announcing Java updates of Apr 2024 for 8, 11, 17, 21, and 22: resources and thoughts
TLDR: The new updates are 1.8.0_411 (aka 8u411), 11.0.23, 17.0.11, 21.0.3, and 22.0.1 respectively). Crazy that there are now 5 current Java releases, I realize. More below, including more on each of them including what changed and the security fixes they each contain (including their CVE scores regarding urgency of concerns), offered in Oracle resources I list below. Oracle calls these updates "critical patch updates" (yep, CPU), but they are in fact scheduled quarterly updates, so that "critical" nomenclature may sometimes be a bit overstated. And as is generally the case with these Java updates, most of them have the same changes and fixes across the four JVM versions, though not always.
For some folks, that's all they need to hear. For others, read on.
