[JDK-8325340](https://bugs.openjdk.org/browse/JDK-8325340) accidentally removed `final` from the `static final DataInputStream.readUTF` method. This has a minor compatibility impact (allows hiding the method in a subclass, while before that would throw an exception at compile time) and since it was not the intent of the prior change to alter any behavioral semantics here I want to revert that change.
