commit a955189d90c3a16340338db8fe87eaf3dad86130
Author: Daniel Sun <su...@apache.org>

    Make inner class `MethodIndex` `static`
    
    A static inner class does not keep an implicit reference to its enclosing instance. This prevents a common cause of memory leaks and uses less memory per instance of the class.
