Error description
Error Message: When getAllByName(String host) is used in z/OS, only IPv6 addresses are returned. The expected behavior is to return all addresses (IPv4 and IPv6) with the addresses listed in the appropriate order based on java.net.preferIPv6Addresses. When it is false (the default), the IPv4 Addresses should be listed first. Otherwise the IPv6 Addresses should be listed first. . Stack Trace: N/A .
Local fix
Problem summary
The problem is specific to z/OS as the corresponding system call for getAllByName() return both IPv4 and IPv6 addresses only when specific flags are set.
Problem conclusion
The JDK has been updated to set the proper flags for the system call to return both IPv4 and IPv6 addresses. . This APAR will be fixed in the following Java Releases: 6 SR16 FP2 (6.0.16.2) 7 R1 SR2 (7.1.2.0) 6 R1 SR8 FP2 (6.1.8.2) 7 SR8 (7.0.8.0) .
