Looks like, root reason being a difference in the FEATURE_COUNT parameter definition between WMS 1.1.0 and 1.3.0. The former states:
7.3.3.7 FEATURE_COUNT FEATURE_COUNT is the maximum number of features for which feature information should be returned. Inclusion of a value for this attribute is optional. When included, the value must be greater than zero. When absent, the amount of information to return is at the server's discretion. Mind to create a JIRA ticket?
