In compiling the latest version of XmlRpcServer.java with javac (1.3.1), I got a compiler error because of the static member 'EMPTY_BYTE_ARRAY' in the inner 'Worker' class. Section 8.1.2 of the Java Language Spec 2nd ed. does specifically state that "Inner classes may not declare static members, unless they are compile-time constant fields." Since EMPTY_BYTE_ARRAY is defined as "= new byte[0]", this is not a compile-time constant and is therefore invalid. Interestingly, the Jikes compiler does not complain about this (perhaps because it is also declared as final?). Alternatively, if the Worker class was a Nested class but not an Inner class (i.e., Worker is 'static' - which doesn't seem appropriate), this would be legal.
I plan to move EMPTY_BYTE_ARRAY back to the outer class in my copy. I ask that someone checks this change into CVS as well. Rick
