The URL pattern "" is invalid

[abitgcp]

Clone the GIT repo in local Eclipse

Expected behavior

In the repository code, url-pattern is empty in web.xml in partnerconsent project.
So, the expectation is that no validation error is shown when url-pattern is empty

Actual behavior

Validation error is shown when url-mapping is empty
See this stack overflow post where I posted this issue first and got the suggestion to create an issue for the repository owner.

Kindly change the repository code if it shouldn't be empty.
