Changelog

Sourced from com.cedarsoftware:json-io's changelog.

4.81.0 (unreleased)

• BUG FIX: Resolver - Fixed array/collection cross-conversion returning null
  • When JSON contained @type=char[] but caller requested byte[].class, json-io returned null instead of converting
  • Same issue affected other array cross-conversions (e.g., byte[] → char[], int[] → long[]) and array ↔ collection conversions
  • Added early conversion logic in toJava() that detects type mismatches and uses the Converter to transform between array/collection types
  • Now properly handles: array → different array, array → Collection, Collection → array
  • Related fix in java-util's Converter (see java-util 4.81.0 changelog)
• FEATURE: Added omitRootTypeInfo() and showRootTypeInfo() to WriteOptionsBuilder
  • Control whether @type is written on the root object when using showTypeInfoMinimal() (the default)
  • omitRootTypeInfo() - Omit the @type on the root object, useful when the reader uses .asClass() or .asType()
  • showRootTypeInfo() - Explicitly show the @type on the root object (current default)
  • Added isShowingRootTypeInfo() getter to WriteOptions
  • Validation: These methods are only valid with showTypeInfoMinimal(). Using them with showTypeInfoAlways() or showTypeInfoNever() throws IllegalStateException — those modes have absolute behavior that cannot be overridden
  • Current default is to show root type (backward compatible), but this will likely change to omit in a future release
  • This allows reducing JSON payload size when the receiving system knows the expected type

4.80.0 - 2025-01-05

• FEATURE: JSON5 Support - Parser now accepts JSON5 extensions by default
  • Added ReadOptionsBuilder.strictJson() for RFC 8259 compliance mode
  • Default is permissive mode (accepts JSON5 features)
  • When strictJson() is enabled, JSON5 extensions cause parse errors
  • Unquoted object keys: Object keys can now be valid ECMAScript identifiers without quotes
    • Keys must start with a-z, A-Z, underscore (_), or dollar sign ($)
    • Subsequent characters can include digits (0-9)
    • Examples: {name:"John"}, {_private:1}, {$jquery:"lib"}
  • Comments: Both single-line and block comments are now supported
    • Single-line comments: // comment until end of line
    • Block comments: /* comment */ (can span multiple lines)
    • Comments can appear anywhere whitespace is allowed
  • Trailing commas: Objects and arrays can now have a trailing comma
    • Objects: {"a": 1, "b": 2,} is valid
    • Arrays: [1, 2, 3,] is valid
    • Nested structures with trailing commas: {"arr": [1, 2,], "name": "test",}
  • Single-quoted strings: Strings can use single quotes instead of double quotes
    • Values: {"name": 'John'} is valid
    • Keys: {'name': "John"} is valid
    • Single quotes can contain unescaped double quotes: {'text': 'He said "Hello"'}
    • Escape single quotes with backslash: {'text': 'It\'s working'}
  • Hexadecimal numbers: Integer literals can be specified in hexadecimal
    • Lowercase: {"value": 0xff} equals 255
    • Uppercase: {"value": 0xFF} equals 255
    • Negative hex: {"value": -0xFF} equals -255
    • Up to 16 hex digits supported (full 64-bit range)
  • Special number formats: JSON5 number format extensions
    • Leading decimal point: {"value": .5} equals 0.5
    • Trailing decimal point: {"value": 5.} equals 5.0
    • Explicit positive sign: {"value": +5} equals 5
    • Combinations supported: +.5 (0.5), -.5 (-0.5), +5. (5.0)
    • Works with exponents: .5e2 (50.0), 5.e2 (500.0), +1e5 (100000.0)
  • Multi-line strings: Strings can span multiple lines using backslash continuation
