There are some functions that explicitly append a slash to URL's (see below), which is not always helpful. I have a client, unfortunately not under my jurisdiction, that refuses to work with my SOAP-service, since the service exports a WSDL-file, generated by CXF, that has a slash appended.

I understand that just skipping the slash probably will affect a plethora of applications that rely on it, so maybe an option could be introduced modifying line 178 in the class: "PackageUtils" to:

• return "http://" + String.join(".", parts) + ((optionNoTrailingSlash) ? "" : '/');

instead of the current:

• return "http://" + String.join(".", parts) + '/';

for example.

Statements that immutably append slashes

The following list is the result of a regular expression search, probably not all of them are relevant.
