Thanks @eskabetxe for your contribution. There are some existing test cases failed with the change and I am planning to look into it once I get time. It would be great if you could take a look what the root cause and fix it. Happy coding!

@stevehu resolved, sorry i take a wile to understand the problem..
there are some issues if the "id" as the same value as "schema" causing some infinite loop

[stevehu]

@eskabetxe Thanks a lot for your help.

@eskabetxe I am wondering if you could help to add a test case for the subschema to ensure other people's changes won't break your code.

[eskabetxe]

I had already thought about it.
The problem is that it will be necessary a url with a valid scheme
Could we use a url to a file in repository (github)?

[stevehu]

Not necessary. I have undertow included in the test scope already and going to start a test server for this purpose. I have some other remote schemas that need to be tested as well. Give me some time and I will put it in. Hopefully this weekend. Thanks for reminding me:)

[stevehu]

@eskabetxe As per our discussion, I have added undertow server in the test for remote references. Let me know if you have any questions. Thanks.
