SpringIOUtils (Grails 6.2.1)

```
@java.lang.SuppressWarnings("unchecked")
public class SpringIOUtils
extends java.lang.Object
```
Simple utility methods for file and stream copying. All copy methods use a block size of 4096 bytes, and close all affected streams when done.
Mainly for use within the framework, but also useful for application code.
