// We compile two versions of the nested StaticIface which contains a call
// to a private interface method. Both versions are compiled to use
// invokeinterface, but one is modified to declare a lower classfile version,
// which makes the use of invokeinterface illegal in that context.
// We run the test twice, each time using a different version of the
// StaticIface class.
