But `IPAddressUtil` is an internal implementation util, so that's what the expectation maybe of that implementation. The change to this test looks OK to me.

FWIW `InetAddress.ofLiteral` accepts the enclosing "[]" because that's what `InetAddress.getByName` does.
And as you noted `sun.net.util.IPAddressUtil.isIPv6LiteralAddress` is an internal API - it parses the literal according to the IPv6 literal syntax (which doesn't include the "[]")

    jshell> InetAddress.getByName("[::1]")
    $1 ==> /0:0:0:0:0:0:0:1
