--- Comment #1 from Craig Rodrigues <rodr...@freebsd.org> --- Previously, I reported some error messages reported by Jenkins on startup: http://lists.freebsd.org/pipermail/freebsd-java/2014-February/010593.html I looked at the Jenkins source code, and isolated the problem. I wrote this simple testcase (see attached MulticastTest.java), which I am also including inline: ================================================================================ /* * To build this test, * (1) Make sure that the OpenJDK is installed from ports: * * pkg install openjdk * * (2) Rename this file to: MulticastTest.java * (3) Build it: * * javac MulticastTest.java * * (4) Run it: * * java MulticastTest.java * */ import java.net.InetAddress; import java.net.MulticastSocket; class MulticastTest { public static void main(String[] args) { try { int PORT = Integer.getInteger("hudson.udp",33848); InetAddress MULTICAST = InetAddress.getByAddress(new byte[]{(byte)239, (byte)77, (byte)124, (byte)213}); MulticastSocket mcs = new MulticastSocket(PORT); mcs.joinGroup(MULTICAST); } catch (Exception e) { e.printStackTrace(); System.exit(-1); } } } ================================================================================ If I run this testcase, I get the same error as what I reported earlier with Jenkins: java.net.SocketException: Invalid argument at java.net.PlainDatagramSocketImpl.join(Native Method) at java.net.AbstractPlainDatagramSocketImpl.join(AbstractPlainDatagramSocketImpl.java:178) at java.net.MulticastSocket.joinGroup(MulticastSocket.java:319) at MulticastTest.main(MulticastTest.java:31) If I run: ktrace java MulticastTest I see that the error here: 13253 java CALL setsockopt(0x4,0x29,0x1b,0x7fffffbfd7dc,0x4) 13253 java RET setsockopt 0 13253 java CALL setsockopt(0x4,SOL_SOCKET,SO_BROADCAST,0x7fffffbfd7d8,0x4) 13253 java RET setsockopt 0 13253 java CALL getsockopt(0x4,SOL_SOCKET,SO_TYPE,0x7fffffbfd77c,0x7fffffbfd778) 13253 java RET getsockopt 0 13253 java CALL setsockopt(0x4,SOL_SOCKET,SO_REUSEPORT,0x7fffffbfd7e0,0x4) 13253 java RET setsockopt 0 13253 java CALL setsockopt(0x4,SOL_SOCKET,SO_REUSEADDR,0x7fffffbfd7e0,0x4) 13253 java RET setsockopt 0 13253 java CALL bind(0x4,0x7fffffbfd7a8,0x1c) 13253 java STRU struct sockaddr { AF_INET6, [::]:33848 } 13253 java RET bind 0 13253 java CALL setsockopt(0x4,0x29,0x9,0x7fffffbfd7f4,0x4) 13253 java RET setsockopt 0 13253 java CALL getsockopt(0x4,0x29,0x9,0x7fffffbfd8ac,0x7fffffbfd864) 13253 java RET getsockopt 0 13253 java CALL setsockopt(0x4,0x29,0xc,0x7fffffbfd8c0,0x14) 13253 java RET setsockopt -1 errno 22 Invalid argument This looks like a bug in the FreeBSD networking code for multicast, or a bug in the FreeBSD code in the OpenJDK. This Java code works under Linux, Solaris, Windows, etc., so it would be good to fix this problem on FreeBSD. Can a networking person help me with this? -- You are receiving this mail because: You are on the CC list for the bug.
