--------------------------
Summary: StringUtils#equals fails with Index OOBE on non-Strings
with identical leading prefix
Key: LANG-1162

Issue Type: Bug

StringUtils.equals(cs1,cs2) delegates to CharSequence.regionMatches(...) in a
way that causes IndexOutOfBounds when either of cs1/cs2 isn't a String.
Specifically, comparing "foo" and "foobar" for non-String CharSequences bombs
due to CharSequenceUtils.regionMatches(cs1, false, 0, cs2, 0,
Math.max(cs1.length(), cs2.length())) because regionMatches doesn't check for
input exhaustion.
