> When the following schema is parsed:
> {code:java}
> Schema schema = new Schema.Parser().parse("{ \"name\": \"test\", \"type\": \"record\", \"fields\": [{ \"name\": \"time\", \"type\": { \"type\": \"long\", \"logicalType\": \"MY_TIMESTAMP\" }}]}");
> {code}
> the `logicalType` is not properly initialized for the schema object of the `time` field. This means that:
> {code:java}
> Schema timeSchema = schema.getField("time").schema();
> assert(null == timeSchema.getLogicalType());
> assert(null != timeSchema.getObjectProp(LogicalType.LOGICAL_TYPE_PROP))
> {code}
> The private schema value representing the logical type is still `null`. However, the property map is properly filled with a `LOGICAL_TYPE_PROP`.
> Such a schema is unusable because the client of the library cannot fix the logical type afterwards.
> {code:java}
> myLogicalType.addToSchema(timeSchema); // BOOM
> {code}
