Description

We are using `rules_jvm` without problems with this in the workspace:
```
load("@contrib_rules_jvm//:repositories.bzl", "contrib_rules_jvm_deps")

contrib_rules_jvm_deps()

load("@contrib_rules_jvm//:setup.bzl", "contrib_rules_jvm_setup")

contrib_rules_jvm_setup()
```

However, as soon as we add `--override_repository= rules_jvm=/path/to/rules_jvm` the build fails with:
```
ERROR: Error computing the main repository mapping: at /Users/.../.cache/bazel/.../external/contrib_rules_jvm/setup.bzl:4:6: cannot load '@@rules_java//java:repositories.bzl': no such file
Computing main repo mapping:
Fetching repository @@contrib_rules_jvm_deps; starting
```

Note, the outer build is running with `--noenable_bzlmod` (Bazel 7.0.1) because we have not migrated yet.

Research direction

Start with the WORKSPACE loading sequence and the external contrib_rules_jvm/setup.bzl location shown in the error, then reproduce under Bazel 7.0.1 with --noenable_bzlmod and --override_repository. Investigate why the override cannot load @rules_java//java:repositories.bzl; done means the override works without that repository-mapping failure while preserving the existing setup.
