Scott Carey commented on AVRO-771:
----------------------------------
We've already had one user with an error caused by 1.5.11 on the same classpath
as 1.6.x. If we upgrade to 1.6.x, we'll fix those already using 1.6.x and
break others. But I suppose that works both ways.
http://www.slf4j.org/faq.html#compatibility
Doing some digging around it looks like many projects have upgraded already,
but others have not. If 1.5.x lasts a while, it should probably be on slf4j
1.6.x.
I'll attach a patch with that change in there too.

> We should consider a newer Jackson version, at least the latest 1.4.x, but

> Junit is a trivial upgrade.
> slf4j has some changes affecting compatibility (but is API compatible) in
> 1.6.x. We may want to delay that one.
> Jetty and Netty can be upgraded.
> The most important one above is Jackson since it is the most likely to have
> classpath collisions. Even though we do not use features from newer
> versions, it might be wise to move to that.
> For plugins, there are these updates:
> [INFO] The following plugin updates are available:
> [INFO] maven-surefire-plugin ................................ 2.7.1 -> 2.7.2
> [INFO] org.codehaus.mojo:exec-maven-plugin ...................... 1.1 -> 1.2
> Both of which seem minor by their release notes.
