All builds are green for me, except AArch64 Zero.

GH actions do not build AArch64 Zero. GH actions build both x86_64 Zero and AArch64 Server. [My CIs](https://builds.shipilev.net/openjdk-jdk/), on the other hand, make a point to build every configuration out there every night -- at expense of CPU time spent on it -- and thus capture even the odd corner cases like these.
