Description

Very similar to #1226, but for rest easy instead.
Created a API Spec with a query parameter of type integer, with format int64 which results to Long in Java. Leads to a broken resteasy Api with the following signature:
@DefaultValue("0l") @QueryParam("offset") Long offset,

openapi-generator version

5.1.0

causing the problem (line of code or commit), or simply make a suggestion -->
remove the suffix for long, float, double etc, as in
#4969
