Review Comment:
minor: consider locating `hideStackTrace` after the two `allow...` to match
protected constructor init order

private final AllowListUrlChecker allowListUrlChecker;

Review Comment:
Wondering if only the `info.add` here could be guarded by the
`!hideStackTrace` hide condition i.e. it's logged but not returned in the
response?

Review Comment:
subjective: with multiple places have this logic, perhaps there could be a
common utility method somewhere
```suggestion
boolean hideStackTrace = SomeWhereUtils.getHideStrackTrace(solrCore);
```
