Hi, during my work on exception sites in the JDK, I spotted another minor place that should be fixed. In the Windows native implementations of DualStackPlainDatagramSocketImpl and DualStackPlainSocketImpl, there are calls to evaluate OS API errors after unsuccessful return of NET_MapSocketOption where this should not be done. Please review my fix. I also took the opportunity to clean up some indentations.
