Doug Cutting commented on AVRO-1126:
------------------------------------

> I propose that we have a canonical representation of schema default values 
> that has no external surface area of a third party library, as part of the 
> Schema API.

I agree.  I proposed the javax.json API for this, the standard Java API for 
immutable JSON data.  We could use generic instead, although I slightly prefer 
something more standard and unchanging.  We might change the generic API and it 
would be better if that only affected applications that use generic data and 
didn't also force all code that touches default values to also change.

Note that default values don't need to have distinct, named types at runtime.  
For example, we could use Map<String,Object> for both records and maps, and 
String for both strings and enum symbols.  Something like this might be a 
better choice than generic.

> Upgrade to Jackson 2+

> Quite annoyingly with Jackson 2+ the base package name has changed from 
> org.codehaus.jackson to com.fasterxml.jackson so in addition to changing the 
> dependencies from:
> {code:xml} 
> <dependency>
>     <groupId>org.codehaus.jackson</groupId>
>     <artifactId>jackson-core-asl</artifactId>
>     <version>${jackson.version}</version>
> </dependency>
> <dependency>
>     <groupId>org.codehaus.jackson</groupId>
>     <artifactId>jackson-mapper-asl</artifactId>
>     <version>${jackson.version}</version>
> </dependency>
> {code} 
> to:
> {code:xml} 
> <dependency>
>     <groupId>com.fasterxml.jackson.core</groupId>
>     <artifactId>jackson-core</artifactId>
>     <version>${jackson.version}</version>
> </dependency>
> <dependency>
>     <groupId>com.fasterxml.jackson.core</groupId>
>     <artifactId>jackson-databind</artifactId>
>     <version>${jackson.version}</version>
> </dependency>
> {code} 
> the base package in the code needs to be updated. More info can be found 
> [here|http://wiki.fasterxml.com/JacksonUpgradeFrom19To20], I am happy to do 
> the work just let me know what is preferable i.e. should I just attach a 
> patch to this issue?
