Nothing throws an exception or otherwise prevent this being negative but that would be a weird usage. Typically the weight is either zero or based on the font size .. which ought not to be negative but I don't think anything prevents it and I think we would treat it essentially as a transform. So If you really want to be careful here, then yes assume weight could be negative. ------------- PR: https://git.openjdk.java.net/jdk/pull/2912
