Previously in JBoss Enterprise Web Server, Java returned IPv6 with a zone value similar to <literal>2001:db8:0:f101::1%2</literal>. Subsequently, when returning a node address, the <parameter>modcluster</parameter> subsystem sent the IPv6 information as it existed in Java. In Solaris, <methodname>apr_sockaddr_info_get()</methodname> did not support the returned format and failed to resolve the IP as a host name. As a result, httpd mod_cluster did not work as expected IPv6 node addresses.
This issue is fixed in JBoss Enterprise Web Server 2.1.
