Committed revision 826370.
Also changed a thrown RuntimeException to be a thrown IllegalArgumentException as RuntimeException's aren't very happy to catch.
> StringEscapeUtils.unescapeJava should support \u+ notation

https://issues.apache.org/jira/browse/LANG-507> Project: Commons Lang
> Issue Type: Improvement
> Affects Versions: 2.4
> Reporter: Gregor B. Rosenauer
> Priority: Trivial
> Fix For: 3.0

>
> Currently, when trying to unescape a String with Unicode escapes in the common notation, e.g., \u+0022, I get a NumberFormatException:
> org.apache.commons.lang.exception.NestableRuntimeException: Unable to parse unicode value: +002
> Note that the number is also parsed incorrectly as it is shortened by one character (obviously, the parser gets confused by the '+' and only takes up to 4 bytes, so it neglects the last digit).
> I am aware that in Java, Unicode is escaped as "\u" followed by 4 bytes that represent the hex code in the Unicode map, but the \u+ notation is commonly used outside the Java world and it would be very handy if StringEscapeUtils supported that, at least as an option.
> Would you please consider adding this feature to 3.0?
