Added printing arrays with java.lang.IO warning.

[gem-bricks]

java.lang.IO was added with JRE 25, which provides the alternative methods print and println. These delegate to the java.lang.System.out PrintStream, and currently, while array printing with out shows a warning, the IO methods do not.

My pull request adds warnings for these methods. Using the hint has the same behavior as the System.out hints.
