Get rid of redundant cast to javax.xml.bind.JAXBElement<java.lang.Boolean> warning from CXF-generated code

Question

I generate some code using CXF from a WSDL-file. When compiling the code with version "1.6.0_16" with the flag -Xlint I get the following warning:

warning: [cast] redundant cast to javax.xml.bind.JAXBElement<java.lang.Boolean>
   [javac]         this.r = ((JAXBElement<Boolean> ) value);

What does the warning mean, should I be worried? As I have generated and not written the code, what can I do to get rid of this specific warning?

Answer 1

No, you should not be worried, redundant casts are harmless.

It's common for generated code to compile with warnings, you generally just ignore them. Better yet, compile the generated code into a separate JAR, and reference that from your main code. That way, you don't need to recompile the generated code, and you won't see the warnings every time.
