[hibernate-issues] [Hibernate-JIRA] Resolved: (HV-376) validateValue() and validateProperty() are too restrictive regarding processable property names

validateValue() and validateProperty() are too restrictive regarding processable property names ----------------------------------------------------------------------------------------------- Key: HV-376 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-376 Project: Hibernate Validator Issue Type: Bug Components: engine Affects Versions: 4.2.0.Beta1 Reporter: Gunnar Morling Assignee: Kevin Pollet Priority: Minor Fix For: 4.2.0.CR1 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].
