native, the nargs - 1 words of arguments and objectref are popped from the operand stack. A new stack frame is created for the method being invoked, and objectref and the words of arguments are made the values of its first nargs local variables, with objectref in local variable 0, arg1 in local variable 1, and so on. The new stack frame is then made current, and the Java Virtual Machine pc is set to the opcode of the first instruction of the method to be invoked. Execution continues with the first instruction of the method.
If the method is native and the platform-dependent code that implements it has not yet been loaded and linked into the Java Virtual Machine, that is done. The nargs - 1 words of arguments and objectref are popped from the operand stack; the code that implements the method is invoked in an implementation-dependent manner.
Linking Exceptions
During resolution of the CONSTANT_Methodref constant pool item, any of the exceptions documented in §5.2 can be thrown.
Otherwise, if the specified method exists but is a class (static) method, the invokespecial instruction throws an IncompatibleClassChangeError.
Otherwise, if the specified method is abstract, invokespecial throws an AbstractMethodError.
Otherwise, if the specified method is native and the code that implements the method cannot be loaded or linked, invokespecial throws an UnsatisfiedLinkError.
Runtime Exception
Otherwise, if objectref is null, the invokespecial instruction throws a NullPointerException.
