The top-level `null` short-circuit in `DefaultValidator.validate(...)` checks `schema.types().contains(NULL)`, so `null` falls through to the switch — which is what we want: `AlwaysSchema` accepts `null` via its case body, `NeverSchema` rejects `null` via its case body. + +## Parser + +`SchemaParser.parse` switches its parameter type from `Map` to `Object`, with a single dispatch added at the top: + +```java +public static Schema parse(Object raw) { + if (raw instanceof Boolean b) { + return b ? new AlwaysSchema() : new NeverSchema(); + } + if (raw instanceof Map map) { + @SuppressWarnings("unchecked") + Map typed = (Map) map; + return parseMap(typed); + } + throw new IllegalArgumentException("schema must be a boolean or an object, was: " + raw); +} +``` + +`parseMap` is the existing body of the old `parse` method, renamed.

The library has no published consumers (`0.0.1-local`), so this is acceptable. Internal callers and tests are all updated in the same PR. +- **Empty-map `items` interaction.** `parseArray` continues to short-circuit `items.isEmpty()` to `NullSchema`. With the new parser, `items: true` would correctly produce `AlwaysSchema` since the input is a Boolean, not a Map.

From 4417cba188762d0c29e8c420b3f249b1fc202bcd Mon Sep 17 00:00:00 2001 From: Thomas Cederholm Date: Fri, 8 May 2026 15:25:41 +0200 Subject: [PATCH 3/8] feat: Parse boolean schemas as AlwaysSchema and NeverSchema JSON Schema 2020-12 allows a bare true or false where a schema is expected: true accepts any value, false rejects every value. Add the two new sealed-hierarchy records and change SchemaParser.parse to accept Object so boolean values dispatch to the new records. Recursive callers (parseObject, parseArray, parseList, NotSchema) and external callers in Spec.java drop their Map casts. AdditionalProperties keeps its existing Boolean handling. DefaultValidator gets minimal switch branches for the two new types.
