Simple String in Elytron rotating-file-audit-log.suffix attribute causes wrong audit file name ---------------------------------------------------------------------------------------------- Key: ELY-1266 URL: https://issues.jboss.org/browse/ELY-1266 Project: WildFly Elytron Issue Type: Bug Components: Audit Affects Versions: 1.1.0.Beta52 Reporter: Ondrej Lukas {{suffix}} attribute of Elytron {{rotating-file-audit-log}} uses {{java.text.SimpleDateFormat}} format [1]. It means that {{'someText'}} can be used as value of {{suffix}} attribute. However in case when only this string (without any pattern letters) is used in {{suffix}}, then resulting audit file name includes suffix "null" instead of defined suffix "someText". In case when suffix includes also pattern letters (e.g. {{d'someText'}}) then it works correctly. [1] https://docs.oracle.com/javase/8/docs/api/java/text/SimpleDateFormat.html
