// so the class names/interfaces are different).

// Java 6:
// sun.awt.color.CMM (as the one and only)
// Java 7:
// sun.java2d.cmm.CMSManager (using default sun.java2d.cmm=sun.java2d.cmm.kcms.CMM)
// sun.java2d.cmm.PCMM
// sun.java2d.cmm.kcms.CMM implements PCMM (similar to Java 6 CMM)
// sun.java2d.cmm.lcms.LCMS implements PCMM
// Java 8:
// sun.java2d.cmm.CMSManager (using default sun.java2d.cmm=sun.java2d.cmm.lcms.LcmsServiceProvider)
// sun.java2d.cmm.CMMServiceProvider (getModule() method, that returns PCMM)
// sun.java2d.cmm.PCMM
// sun.java2d.cmm.kcms.KcmsServiceProvider
// sun.java2d.cmm.kcms.CMM implements PCMM (similar to Java 6 CMM)
// sun.java2d.cmm.lcms.LcmsServiceProvider
// sun.java2d.cmm.lcms.LCMS implements PCMM
// TODO: Consider a different option, invoking CMSManager.getModule() through reflection to get actual used instance
// Default to using a NullSanitizerStrategy on non-Sun/Oracle systems?
