BuiltInTopic data parser is implemented, which generates UserDataQos and BuiltInTopicKey.
JS callback function is invoked on new participant.

The build failed in ./run-test.pl. But this error was not there when tested in local.

Which version of node are you using to test locally? We probably need to configure Travis CI to use the Node 6.x LTS version.

I used Node 8.x

Please try changing .travis.yml on your branch to have
node_js: "6"

https://docs.travis-ci.com/user/languages/javascript-with-nodejs/
We could try other versions too, so far we have used 6.x.

If you run multiple times on your local build, do any of them fail the same way that the Travis build did?

I forgot to unsubscribe to the ParticipantBuilTopicDataReader. That's why the process didn't exit properly and got a timeout error.
Checked that in.
