getInvokeSpecialHandle

public Object getInvokeSpecialHandle(Method method,
                                     Object receiver)

Description copied from interface: VMPlugin

Returns a handle with bound receiver to invokeSpecial the given method. This method will require at least Java 7, but since the source has to compile on older Java versions as well it is not marked to return a MethodHandle and uses Object instead

Specified by:

getInvokeSpecialHandle in interface VMPlugin

Overrides:

getInvokeSpecialHandle in class Java7

Returns:

null in case of jdk<7, otherwise a handle that takes the method call arguments for the invokespecial call
