Java's Regex have issue with character classes when it comes to unicode content (

Apparently they solved things in Java7 by adding a special flag: UNICODE_CHARACTER_CLASS ( )

Sadly org.elasticsearch.common.regex doesn't "understand" it. As Java7 is the recommended runtime for ES I think it's OK to add it even if not supported by earlier JDK.
