Java API equivalents for methods in org.apache.commons.io.IOUtils

[Dan S]

I noticed  there are many instances  where org.apache.commons.io.IOUtils
methods are used throughout the code.
e.g. toString, toByteArray, copy, closeQuietly etc. Since Java 9 there are
equivalents for  toString, toByteArray and copy. For closeQuietly a try
with resources can be used to ensure the stream is closed. Would we want to
change over the use of IOUtils methods in favor of Java alternatives?
