Character.codePointAt and codePointBefore have two versions: one which only
accepts an offset, and one which accepts an offset and a limit. The former can
be dangerous when working with buffers of characters because if the offset
is the last char of the buffer, a char outside the buffer might be used to
compute the code point, so one should always use the version which accepts a
limit.
Collections.sort is wasteful on random-access lists: it dumps data into an
array, sorts the list and then adds elements back to the list. However, the
sorting can easily be performed in-place by using Lucene's
CollectionUtil.(merge|quick|tim)Sort.
This commit integrates the forbiddenAPI checks that checks
Java byte code against a list of "forbidden" API signatures.
The commit also contains the fixes of the current source code
that didn't pass the default API checks.
See https://code.google.com/p/forbidden-apis/ for details.
Closes#3059
