Research direction
The report names java-feign, Tomcat 9 on JDK 8, and Jackson 2.10.x; start by reproducing the ClassFormatException in that environment and tracing which generated-client or dependency-loading entry point is involved. Identify the relevant generator test location, then verify that Java 8 and Tomcat 9 handle the generated output without the reported constant-pool error.
