    If only there were a spec for ping that would tell you whether such
    an address should be rejected...   :-)

Agreed, but Linux rejects it and OSX does not (!).

Linux:

$ ping 1271.1.2.3

ping: 1271.1.2.3 Name or service not known.

OSX:

$ ping 1271.1.2.3

PING 1271.1.2.3 (92.242.140.21): 56 data bytes

Request timeout for icmp_seq 0

Request timeout for icmp_seq 1

Request timeout for icmp_seq 2

(etc.)

Valid syntax, but not a valid address.

Turns out to have nothing to do with ALPN - Linux says 1271.1.2.3 is not a valid IP address; OSX thinks it is - so a unit test that passes on Linux fails on OSX

I haven't seen the error message referred to so not sure of the context.

However to get ALPN to work generally you need to add the appropriate grizzly-alpn jar to the bootclasspath of the server. Which version depends on the exact JDK build number you're on.

Subject: [glassfish-dev] "TLS ALPN (Application-Layer Protocol Negotiation) support is not available. HTTP/2 support will not be enabled" in Grizzly tests?

What JDK do you need to get this to work? The latest JDK8 I can find is build 241

Thanks,
