Would you make it package-private?

Review Comment:
`InterruptedException` is not thrown in this method and should be removed.
This class is annotated `@Public` and the change may cause compile error. Also,
we can remove the below code from the test code.
```
try {
mos.close();
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
```
