org.eclipse.persistence.internal.libraries.asm.MethodVisitor.visitMethodInsn()
Visits a method instruction. A method instruction is an instruction that invokes a method. @param opcode the opcode of the type instruction to be visited. This opcode is either INVOKEVIRTUAL, INVOKESPECIAL, INVOKESTATIC or INVOKEINTERFACE. @param owner the internal name of the method's owner class (see {@link Type#getInternalName() getInternalName}). @param name the method's name. @param desc the method's descriptor (see {@link Type Type}).

                // if this is a primitive, get the wrapper class
                String wrapper = ClassWeaver.wrapperFor(attributeDetails.getReferenceClassType().getSort());
                if (wrapper != null) {
                    // Call valueOf on the wrapper (more optimal than
                    // constructor).
                    cv_get.visitMethodInsn(INVOKESTATIC, wrapper, "valueOf", "(" + attributeDetails.getReferenceClassType().getDescriptor() + ")L" + wrapper + ";");
