[jboss-jira] [JBoss JIRA] Resolved: (JGRP-817) MethodCall: match between formal parameters and actual arguments fails if an argument is a subtype of a parameter

MethodCall: match between formal parameters and actual arguments fails if an argument is a subtype of a parameter ----------------------------------------------------------------------------------------------------------------- Key: JGRP-817 URL: https://jira.jboss.org/jira/browse/JGRP-817 Project: JGroups Issue Type: Bug Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.6.4, 2.7 If we have class Foo with method: public class Foo { public void bar(Object a, String b) {} } then MethodCall fails if we invoke: dispatcher.callRemoteMethods(null, "bar", new Object[] {"hello", "world"}, new Class[]{String.class,String.class}, ...); because the first formal parameter of foo() is an Object and the arg a String, and we do an equals() on the 2 classes. Solution: use Class.isAssignableFrom(Class)
