Description

Name: acR10002			Date: 08/14/2001



This bug is filed for tracking purposes only:

The problem has been initially reported in the bug 4377103 which, in it's turn,
has been closed as a duplicate of Solaris bug #4381708. The problem is that
MulticastSocket doesn't receive a datagram packet sent to a localhost via
loopback interface. Though the bug 4381708 has been fixed for Solaris 2.9, the
problem still exists for JDK when running on Solaris 2.8. Since the latter
configuration is assumed to be RI for J2SE, the valid BugID is needed to
exclude the JCK tests. Please, don't close this bug report unless it is
definitely needed.

Comments
EVALUATION We are dependent on a Solaris 8 patch to fix this issue. As noted by the submitter this has been fixed in Solaris 9 (at our request) and we have also requested a patch for Solaris 8. Note that the issue applies to both IPv4 and IPv6 multicasts through the loopback. We also have an issue on Linux with IPv6 multicasts. ###@###.### 2001-08-14 In tiger it would desirable to programmatically determine if an interface supports multicasting - this is one of the items tracked in 4691932. ###@###.### 2002-07-18 There is a patch for Solaris 8: 108528-21. The JCK team should retest after installing the patch. Meanwhile, I will notify the product team to include the patch number in the patch-list for Solaris 8. ###@###.### 2003-10-13 Name: acR10002 Date: 10/17/2003 Provided with the Solaris 8 patch 108528-21, the exaple from 4377103 no longer fails. ======================================================================
