      Description

        In case of openjdk, ColorComverOp does not transfer alpha channel
        from a source image to a destination image. Attached test demonstrates
        the problem.

        Although specification for the ColorConvertOp class does not define
        how alpha channel should be handled, the oracle jdk (which is based
        on kcms) transfers the alpha correctly. So, current behavior of openjdk
        can be interpreted as a bug.
