We don't have any such detector in FindBugs, as far as I know.

The main problem I see in writing a detector for this problem
is that FindBugs doesn't know whether or not conversions which
lose precision were written explicitly by the programmer,
or generated by javac.

This might be another case where using a source-based tool
such as PMD would be the easiest way to detect the problem.
