repro note: requires workspace. USE_BAZEL_VERSION=last_green bazel build ... --enable_bzlmod=false --enable_workspace=true

[rickeylev]

Figured out the issue: https://github.com/bazelbuild/rules_java/issues/128

We just need to update the rules_java used for workspace. bzlmod automatically picked up 7.11.1. Workspace was using something much earlier (5-something I think I saw).

Well, upgrading the java version fixes part of it, but now there are errors about finding toolchains. (this is all with bazel@head). I guess that's a separate issue, though.
