It is possible to create constant-name-rewriter without defined constant ------------------------------------------------------------------------ Key: WFLY-7670 URL: https://issues.jboss.org/browse/WFLY-7670 Project: WildFly Issue Type: Bug Components: Security Reporter: Jan Tymel Assignee: Darran Lofthouse Labels: user_experience Fix For: 11.0.0.Alpha1 If user adds a new {{constant-name-rewriter}} via following command {{/subsystem=elytron/constant-name-rewriter=name-rewriter:add(constant)}} then is a new rewriter created. It shouldn't be possible since {{constant}} attribute isn't filled correctly. However, there is added a new rewriter with {{true}} value [1] instead. [1] <constant-name-rewriter name="name-rewriter" constant="true"/>
