2. In schema i have construction like "$ref": "#/definitions/deleteSchema"
3. I open schema ResourceLoader resourceLoader ; .... Json.Schema schema = Json.schema(resourceLoader.getResource("classpath:" + jsonSchemaFile).getURI());
4. I have NPE

Can you give me complete schema files that reproduce the problem. It'll save me some time to debug. Also, are you using 1.3 stable or 1.4 snapshot?

I just added a test with this case (see src/test/resources/schema_with_defs.json) and the unit test in TestSchemas.java

It seem to be working some I'm closing this as working. If you have a use case that shows the problem with the latest code, let's look at it!
