Wrong default value for BigDecimal

[JureVI]

It seems that if useBigDecimals is set to true and a numeric field has default property set, the generated Java file has the field initialized with Double value instead of BigDecimal.

Json schema:

...
"amount": {
  "type": "number",
  "default": 0,
  ...
}
...

Java file:

...
@SerializedName("amount")
@Expose
private BigDecimal amount = 0.0D;
...

This is my gradle configuration:

jsonSchema2Pojo {
    generateBuilders = false
    usePrimitives = false
    source = ...
    targetDirectory = ...
    targetPackage = ...
    propertyWordDelimiters = [] as char[]
    useLongIntegers = false
    useBigDecimals = true
    includeHashcodeAndEquals = true
    includeToString = true
    includeJsr303Annotations = false
    sourceType = 'jsonschema'
    removeOldOutput = true
    outputEncoding = 'UTF-8'
    useJodaDates = false
    useCommonsLang3 = false
    initializeCollections = false
}

This could be fixed in DefaultRule.getDefaultValue. Should we parse BigDecimal like this?

JInvocation newBigDecimal = JExpr._new(fieldType);
newBigDecimal.arg(JExpr.lit(Double.parseDouble(node.asText())));
return newBigDecimal;

I think it might be better to use the String constructor of BigDecimal, since it avoids a multitude of numeric representation issues and will create a BigDecimal that matches number given in the JSON Schema exactly.
