Right, but mostly is not all. For example test/com/sun/net/httpserver/Test1.java should no longer include @library /lib/testlibrary. It depends only on SimpleSSLContext which is being moved.  It is easy to see this by looking at the imports. 

Whatever script you have for updating these tests should also remove redundant values in the @library tag. I suspect there are a significant number of these ( a lot of tests just use one library class ).

Just on that, is it for a library class to indicate that it depends on a class from another library? I believe this is the case for some library utilities. How can a test know this. It needs to be a library class that indicates this dependency.I see nothing in the webrev for this ( or maybe I missed it ).
