Per Oracle docs, "The Java Authentication and Authorization Service (JAAS) was introduced as an optional package (extension) to the Java 2 SDK, Standard Edition (J2SDK), v 1.3. JAAS was integrated into the J2SDK 1.4." Unless Oracle decides to remove it again, this statement seems likely to be true for the indefinite future. Though now that I think about it, I don't really see how this helps to to tell Maven about dependencies provided by the JDK or the VM. If you're in a VM that includes them, this is unnecessary and if you're not then a system dependency doesn't help since it's not there. Maybe if you're compiling with JDK 1.5 but targeting 1.3 or something like that? -- This is an automated message from the Apache Git Service.
