[java] String#rindex with Regexp
[java] - behaves the same as String#rindex(string) for escaped string
regexps
[java] - returns the index of the first match from the end of string of
regexp
[java] - sets $~ to MatchData of match and nil when there's none
[java] - starts the search at the given offset
[java] - starts the search at offset + self.length if offset is negative
[java] org.jcodings.specific.UTF8Encoding:44:in `length':
java.lang.ArrayIndexOutOfBoundsException: -1
