> In many places standard charsets are looked up via their names, for example:
> absolutePath.getBytes("UTF-8");
>
> This could be done more efficiently(up to x20 time faster) with use of
> java.nio.charset.StandardCharsets:
> absolutePath.getBytes(StandardCharsets.UTF_8);
>
> The later variant also makes the code cleaner, as it is known not to throw
> UnsupportedEncodingException in contrary to the former variant.
>
> This change includes:
> * demo/utils
> * jdk.xx packages
> * Some places were missed in the previous changes. I have found it by
> tracing the calls to the Charset.forName() by executing tier1,2,3 and desktop
> tests.
>
> Some performance discussion: https://github.com/openjdk/jdk/pull/5063
>
> Code excluded in this fix: the Xerces library(should be fixed upstream),
> J2DBench(should be compatible to 1.4), some code in the network(the change
> there are not straightforward, will do it later).
>
> Tested by the tier1/tier2/tier3 tests on Linux/Windows/macOS.
