WebComponent.filterFormParameters reports confusing warning

We see a lot of these warnings in our logs:

> org.glassfish.jersey.servlet.WebComponent: A servlet request to the URI https://example.com/foo?bar=baz contains form parameters in the request body but the request body has been consumed by the servlet or a servlet filter accessing the request parameters. Only resource methods using @FormParam will work as expected. Resource methods consuming the request body by other means will not work as expected

It is a POST request with a query parameter and an empty post-body.
I don't think that any filter is consuming the request body or accessing the request parameters.

Is it possible that the warning is wrong in this case?
