Changeset: 8084b9d08678 Author: Greg Lewis <glewis@eyesbeyond.com> Date: 2012-08-04 10:32 -0700 URL: http://hg.openjdk.java.net/bsd-port/bsd-port/jdk/rev/8084b9d08678 . Try harder to make sure the flags returned from getFlags isn't negative, since a number of places in the code check for that and assume that it means an error occurred. On FreeBSD, in particular, the value of ifr_flags can be negative if multicast is enabled on the socket since the possible flags have expanded to fill more than a short. Instead of blindly promoting ifr_flags to an int, which will preserve the sign, we fill the int return value with ifr_flagshigh in the high 16 bits and ifr_flags in the low 16 bits. ! src/solaris/native/java/net/NetworkInterface.c
