That's kind of annoying... It appears that both implementations of
resolveURI only work with (i.e., return something useful for) relative
URIs , which can just as nicely be represented as paths...

Looking at the implementation I imagine that you're supposed to pass in
new URI("$%7BPROJECT_LOC%7D/file/in/project")...

I think that if you used this constructor, it would escape the braces
and it looks like
java.net.URI uri = new java.net.URI(null, "${x}/y", null);
System.out.println("###" + uri.getRawSchemeSpecificPart());
System.out.println("###" + uri.getSchemeSpecificPart());
