 package org.jruby.internal.runtime.methods;
 
A DynamicMethod backed by one or more java.lang.invoke.MethodHandle objects. The MethodHandles contained in this method are used by invokedynamic-based call site binding to bind more directly to the target. Previously, the handles required for binding were built at the call site by inspecting the DynamicMethod that came in. With the newer logic, handles are created at bind time, so they're already ready and so we don't need to generate our own handle classes that might only get used by the interpreter.
