Work Description: mxm commented on pull request #8424: [BEAM-7170] Fix exception when retrieving ExpansionServer port after closing
URL: https://github.com/apache/beam/pull/8424
The ExpansionServer can throw the following exception after shutdown because the
port getter retrieves the port dynamically from the underlying service:
```
java.lang.IllegalStateException: Already terminated

```
