I'm trying to use OpenFegin in my application but when I run the SpringBoot application, I get the following Exception.
OpenJDK 64-Bit Server VM warning: Options -Xverify:none and -noverify were deprecated in JDK 13 and will likely be removed in a future release.

I tried to debug and found this.
I'm not using OpenFeign Micrometer but I already have 'Micrometer' in my project. I tried disabling the metrics with feign.metrics.enabled=false also but no difference.
I'm running on AdoptOpenJDK 14, my application is a Kotlin app.
I'm not sure if this is related to Micrometer or a totally different issue. How I can resolve this?
