[DO NOT MERGE] Test: build WITHOUT OpenRewrite (no FQCNs)

[gnodet]

Test PR to measure CI build time when OpenRewrite is not triggered.

Contains a trivial Javadoc change with no FQCNs — the regen.sh check should skip OpenRewrite.

Companion to the "with FQCN" test PR for comparison.

DO NOT MERGE — close after measuring build times.
