Hi, Please find a patch that fixes some of the network test to stop the using the wildcard issue whenever possible.
8227539: Replace wildcard address with loopback or local host in tests - part 20 https://bugs.openjdk.java.net/browse/JDK-8227539 webrev: http://cr.openjdk.java.net/~dfuchs/webrev_8227539/webrev.00/ test/jdk/java/net/MulticastSocket/NoLoopbackPackets.java is the outlier here. It's been observed failing because it was receiving packets it didn't expect. The test is modified to skip packets that were not sent by the test. This is achieved by making the payload pseudo-unique. best regards, -- daniel
