With the integration of https://github.com/springdoc/springdoc-openapi/pull/1835 and the release of 1..6.12 there is a problem at the following line: https://github.com/springdoc/springdoc-openapi/blob/499e42c981e4977b48b98c683adf60177a96ea8d/springdoc-openapi-common/src/main/java/org/springdoc/core/MethodParameterPojoExtractor.java#L179 Error: Cannot invoke "java.lang.Class.getName()" because the return value of "java.lang.Class.getSuperclass()" is null Looks like there should be some guard that catches the situation when paramClass.getSuperclass() is null.
