This is not sufficient I believe, we need to basically replace the instanceof checks with a test on the type and types. It would probably make sense to have some helper method working for both 3.0 and 3.1

so something like

boolean isStringSchema(Schema schema) {
 return "string".equals(schema.getType()) ||" (schema.getTypes() != null && schema.getTypes().contains("string")
}

and so on.
you would then use that instead e.g. of else if (property instanceof StringSchema) {

the same goes for array, number etc.

Also it would be probably a series of if, not else, as in oas 3.1 we could have type = "integer, string" so both can be applied

minor: please add spaces after and before { and }

The same would apply below for pattern
