Description

### Description of the bug:

I was doing a `bazel test` and got

```
Computing main repo mapping:

Server terminated abruptly (error code: 14, error message: 'Socket closed', log file: '/private/var/tmp/_bazel_sluongng/06e573a93bc2d6a9cad4ad41f00b4310/server/jvm.out')
```

Then this file appeared in my repository with the JVM crash details:

[hs_err_pid16796.log](https://github.com/user-attachments/files/16846712/hs_err_pid16796.log)

It seems like the crash has something to do with `net.starlark.java.eval.MutableStarlarkList`

Research direction

Start by inspecting the attached hs_err_pid16796.log and the Bazel 7.3.1 crash context around net.starlark.java.eval.MutableStarlarkList. Try to reproduce the failure with bazel test on macOS, though the report says it is not reliable. Done means identifying the crash cause and providing a verified fix or regression test.
