[OmniFaces utilities 2.0] Close a Closeable resource


[OmniFaces utilities] The close() method check if the given resource is not null and then close it, whereby any caught IOException is been returned instead of thrown, so that the caller can if necessary handle (log) or just ignore it without the need to put another try-catch.

Method:
Usage:

import org.omnifaces.util.Utils;
import java.io.IOException;
...
IOException close = Utils.close(closeable_resource);

The closeable_resource is the Closeable resource to be closed. If you are using the Java 7 try-with-resources then closeable resources are automatically closed at the end of the statement. But, this method can be used to "force" the close operation before the end.
