Varargs: jakarta.el.MethodNotFoundException

I encountered the following exception when testing the code below on Wildfly 24."

Tomcat had updated their varargs handling in BZ 65358, and I'm wondering if this API could have something similar applied?

However, I understand this might also be due to vagueness in the spec? Enum could be coerce to a string? I appreciate any assistance. Thanks!
