@WebFilter annotation with servletName attribute cannot be deployed

[38leinaD]

I have a servlet filter without an explicit url mapping, but servletNames set to a valid/existing servlet (defined via web.xml):

@webfilter(filterName = "MyFilter", servletNames = "myservlet", asyncSupported = true)
public class MyFilter implements Filter {}

Expected behavious
As per the Servlet spec, the filter should be able to deploy based on the provided serveltNames attribute :

Actual behavior

The build fails with this exception because the @webfilter annotation does not define an urlMapping:

Build failure: Build failed due to errors
