The buildtools (java tools needed to be run during the build) have long
been plagued by warnings, includuing deprecations and unchecked
warnings, which cannot be silenced during the build.
This patch fixes all buildtool warnings. Most of the warnings are fixed
properly, but a few have had their warnings suppressed locally.
For two tools, cldrconverter and tzdb, I gave up to get them fully
fixed, and instead suppressed warnings in some places. Common for both
these tools were that they used collections of some kind, with a mixed
bag of data types (e.g. a Map from String to either String, HashMap,
ArrayList and String[]). I'm frankly not sure how this could ever have
worked :-) but I assume that the data files being parsed has a structure
that "guarantees" that this works.
Two files in generatecharacter were missing a proper copyright header. I
noticed this when I were about to update the copyright year, and when I
checked the other files I noted another one without header. While I did
not need to change this file, I thought it was suitable to fix the
missing header for both files.
I have verified that the code generated by the build is identical with
and without this patch.
