Review comment:
```
@deprecated As of 2.6 deprecated without replacement. Please use the
try-with-resources statement or handle
suppressed exceptions manually.
```
All our original logic is suppressing `IOException`, so I think we can reuse
`JavaUtils. closeQuietly` directly If all modules can access it.
