Have you considerd using the acceptance tests to confirm compliance to the specification?

I am using a set of test cases from another java library now. If you have links to official test cases, please let me know. Thanks.

Apologies. The official test cases can be found at https://github.com/json-schema-org/JSON-Schema-Test-Suite

@Relequestual I am using the exact test suite and you can find them in the test resources folder.

Great! I didn't dig to find out, sorry.
You might consider adding the fact that you use the official acceptance testing test sets, and how you perform in those tests.
