Description
ADDITIONAL SYSTEM INFORMATION :
OS X 11.5.1

$ java -version
openjdk version "17.0.1" 2021-10-19
OpenJDK Runtime Environment (build 17.0.1+12-39)
OpenJDK 64-Bit Server VM (build 17.0.1+12-39, mixed mode, sharing)

Older versions are also affected (tested 11.0.8)

A DESCRIPTION OF THE PROBLEM :
Method java.beans.Introspector.getBeanInfo(...) sometimes thows exception for complex classes. Issue JDK-8211147 made MethodInfo.MethodOrder comparator antisymmetric, but it is still non-transitive. Attached source code shows an example that breaks transitivity.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run program many times (1000 should be enough, maybe more if not lucky), public API test should throw IllegalArgumentException

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expected to not throw.
ACTUAL -

Public API:

Exception in thread "main" java.lang.IllegalArgumentException: Comparison method violates its general contract!
