I've got similar tags in different taglibs ("title" for example), they differ with their attributes. In such code:
selects attribute names in "<entry:title image="entry" type=""/>" with red, as it thinks, that it is a tag from "jd" taglib, not from "entry" taglib.
Build 4069, Windows. But in linux behaviour is the same.
