Hi folks, did anyone take a look at JIRA ticket BEANUTILS-273? I've attached a patch for this issue as well.
The problem occurs when you anonymously subclass a class overriding a public method. If that method was not declared in any interface by superclass chain, beanutils fails trying to access it. In my patch, I adjusted MethodUtils.getAccessibleMethodFromInterfaceNestto check for that method on superclass chain, besides interfaces from superclass chain (which was already done). Let me know if I could help with something else. Cheers, Marcelo Liberato
