In jdk 9 we started to sort the list of methods for each class for a few reasons, and the main one was:
 1. We had a number of bugs which state that our JavaBeans randomly does not work, examples: JDK-6807471[1] , JDK-6788525[2], the reason was that the order of methods from Class.getMethods() is not specified.

So MethodOrder is just a workaround to help us reproduce the bugs. I understand how the current change will fix the problem, but it would be nice to update the code that retrieves the method from that list, or at least provide some information why we can't do that.

Example from the past https://github.com/openjdk/jdk/pull/7190 where MethodOrder was simplified due to JDK-8196373
