As part of JDK-8176795 we made changes to XRSolidSrcPict.prepareSrcPict() which made conversion of Non-Premultiplied color to Premultiplied color code present in XRColor.setColorValues() as unreachable.

We should remove this dead code and its corresponding second argument "boolean pre" from XRColor.setColorValues() and make relavant changes at other places.
