After calling the function NET_MapSocketOption no runtime error shall be expected, since this is only about mapping some option codes by iterating over a structure.However, in 2 Windows socket implementation files, there are places where the exception generator functions that evaluate runtime errors are called. (JNU_ThrowByNameWithLastError instead of JNU_ThrowByName).The files are:java.base/windows/native/libnet/DualStackPlainDatagramSocketImpl.cjava.base/windows/native/libnet/DualStackPlainSocketImpl.c
