Actually, Reference seems to have some odd behavior in general when constructed
with baseRef. Depending on the construction one may end up with null values, odd
values, wrong URIs, NullPointerExceptions, and infinite loops resulting in
StackOverflowErrors.
Here are my test cases:
Reference host = new Reference("http://host.com";)
scheme: http
authority: host.com
path: null
baseRef: null
rel-part: java.lang.StackOverflowError
rem-part: http://host.com
toString: http://host.com
targetRef: http://host.com
Reference slashdir = new Reference(host, "/dir")
scheme: null
authority: null
path: /dir
baseRef: http://host.com
rel-part: /dir
