with IP "0.0.0.0" - it either does nothing and ping fails, or, in some virtual environments is treated as the default route address. - IPv6 support for ::1 is available since 1977; however, ::0 is not accepted as a vaild psuedo IPv6 address. '::1' must be used instead.

This came to light because some systems failed with IPv4 (those that passed replaced 0.0.0.0 with the default router. but most just fail - not substituting 0.0.0.0 with 127.0.0.1. However, InetAddress.getByName("") returns 127.0.0.1 which compares well with other platform's behavior. ------------- Commit messages: - AIX: InetAddress.getByName(addr) does not work as expected with IP "0.0.0.0" Changes: https://git.openjdk.java.net/jdk/pull/7013/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=7013&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8280498 Stats: 13 lines in 1 file changed: 11 ins; 0 del; 2 mod Patch: https://git.openjdk.java.net/jdk/pull/7013.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/7013/head:pull/7013 PR: https://git.openjdk.java.net/jdk/pull/7013
