I think this should about cover the situation... (😉)... HTH... Dave

void

   * This happens during the java core tests if the message
   * dictionary is missing newly added xxx_reply_t messages.
   * Should never happen, but since I shot myself in the foot once

   * it again... (;-)...

      clib_warning ("Did you forget to call setup_message_id_table?");

Subject: [vpp-dev] jvpp core future test failure (gerrit 8743)

Dear Ole,

See https://gerrit.fd.io/r/#/c/8743. It turns out that the java core future 
“make test” test fails as shown below.

The patch adds three xxx_reply_t binary api messages. See 
.../src/vnet/dns/dns.api.

It sure looks like the Java code knows about them, but isn’t doing a very good 
job of registering them. Note that I had to modify the binary API client 
library to keep Java from ASSERTing due to the NULL msg id’s squawked below.

What’s going on here? These messages work like a champ in vpp_api_test...
