Windows: `bazel clean --expunge` sometimes causes Bazel server to crash

When I run `bazel clean --expunge` on Windows, I sometimes get
```
INFO: Starting clean (this may take a while). Consider using --expunge_async if the clean takes more than several minutes.

Server terminated abruptly (error code: 14, error message: '', log file: 'c:\tmp\_bazel_pcloudy\2a_d8ear/server/jvm.out')
```
Both errror_message and log file are empty.

Bazel version: HEAD
