When I compile the Spring JDBC source on OS X with JDK 1.7.0, I get this warning:

warning: CachedRowSetImpl is internal proprietary API and may be removed in a future release

How do I suppress the warning message during a compile?

I already know and use Java’s @SuppressWarning annotations. I’m looking for the specific use of this to suppress the warning I’ve described.

My question specifically is, in this line of code:

@SuppressWarnings("valuegoeshere")

what should “valuegoeshere” be replaced with?

EDIT: People, I know that it is best to avoid the code that leads to the warning. And usually that would be my approach. However I’m compiling third-party code here which I don’t want to rewrite. I just want to add the correct annotation to suppress the warning, so that warnings I can actually do something about don’t get buried.

    This particular warning cannot be suppressed. At least not officially.

    The warning about proprietary API means that you should not
    use the API which causes the warning. Sun does not support
    such API and the warning will not be suppressible.

    If you’re particularly determined, you can use the highly undocumented javac -XDignore.symbol.file flag which will compile your program against Sun’s internal rt.jar rather than the public-facing symbol file ct.sym. rt.jar doesn’t produce this warning.
