StandardCharsets can be used

Browse Source 
Reports methods and constructors where constant charset String literal is used (like "UTF-8") which could be replaced with a predefined Charset object like StandardCharsets.UTF_8. This may work a little bit faster, because charset lookup becomes unnecessary. Also catching UnsupportedEncodingException may become unnecessary as well. In this case the catch block will be removed automatically.
