RESTEasy: Empty cfg. param javax.ws.rs.Application produces exception --------------------------------------------------------------------- Key: WFLY-950 URL: https://issues.jboss.org/browse/WFLY-950 Project: WildFly Issue Type: Bug Components: REST Reporter: Pavel Janousek Assignee: Weinan Li RESTEasy can be configured through several configuration options in WAR application deployment file WEB-INF/web.xml. The major one (also portable defined by JAX-RS standard) is _javax.ws.rs.Application_. When I set this parameter to empty content present behavior is raising exception "java.lang.StringIndexOutOfBoundsException: String index out of range: 0", it is not so good. I think, this is hard miss-configuration error and deployment description as this one should be rejected and a such application should not be deployed at all with appropriate error message, but not only by messed exception.
