[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-6817) Logging of strings containing the percent character broken

Logging of strings containing the percent character broken ---------------------------------------------------------- Key: HHH-6817 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6817 Project: Hibernate Core Issue Type: Bug Affects Versions: 4.0.0.CR6 Environment: HSQLDB 2.2.6 snapshot Reporter: Fred Toussi Priority: Blocker Fix For: 4.0.0.next, 3.6.next The method AbstractTypeDescriptor#extractLoggableRepresentation(T value) does not escape the percent character. Possible workaround below: public String extractLoggableRepresentation(T value) { if (value == null) return null; String stringValue = value.toString(); return stringValue.replace("%", "%%"); } The return value is used for logging, where the string is used as the format argument to java.lang.String#format(String format, Object... args). The percent character is interpreted as a format identifier and causes an exception as what follows is not necessarily a valid format template.
