The array of tags in the docblock constructor should only contain tags.
Some of the factory methods of the tags are returning a null when the tag could not be created.
This causes issues during parsing. By filtering these null values in the factory this use is resolved.
Due a hotfix done in the the type resolver library version 0.1.5 is the new minimal version of type-resolver.
Without this fix an infinitive loop is created when the use keyword is used in a class.
