Reflection free serializers ArrayIndexOutOfBoundsException

[burl21]

Describe the bug

When updating from version 3.15.1 to 3.16.2, the build fails due to the property:

quarkus.rest.jackson.optimization.enable-reflection-free-serializers=true.

In JacksonCodeGenerator at line 284, the check passes, but set is the name of a field rather than a method prefix.

record ExampleRequestBody(boolean required, boolean set) {}

Stack Trace
