> The methods Validator#validateValue() and Validator#validateProperty() expect the name of a bean property, for which constraint validation should be performed.
> Currently not all valid Java property (field/method) identifiers are supported here, as the specified property name is processed in PathImpl with a regular expression, that matches only the word character class (A-Za-z0-9_), causing the evaluation of uncommon but yet valid property names such as the following ones to fail:
> * private String höchstBetrag; // German Umlaute such as "ö" are allowed in Java identifiers
> * private String €Amount;  // some currency signs such as "€" are allowed, sigh
> * private String höchst\u00f6Betrag; // specifying letters such as "ö" using Unicode is allowed
> Trying to do so results in the following exception:
> {code:java} 
> java.lang.IllegalArgumentException: Unable to parse property path ö
> at org.hibernate.validator.engine.PathImpl.parseProperty(PathImpl.java:216)
> at org.hibernate.validator.engine.PathImpl.createPathFromString(PathImpl.java:64)
> at org.hibernate.validator.engine.ValidatorImpl.validateValue(ValidatorImpl.java:152)
> {code} 
> More information on the identifiers allowed in the Java language can be found in [JLS, chapter 3.8|http://java.sun.com/docs/books/jls/third_edition/html/lexical.html#3.8].
