I was trying to display all method name for a class. This code works fine in sent os 6,
private static void extractClassMethods(Class classObject) {
// read the methods
Method[] methods = classObject.getMethods();
// no methods
if (methods == null) {
return;
}
// print method path
for (Method method : methods) {
System.out.println(method.getName()) ;
}
}
Find the complete exception log,
