Robert Joseph Evans commented on STORM-1202:
--------------------------------------------

My plan is not working as I had hoped.  New clients submitting both old and new 
jars work well, but the old client submitting an old jar results in 
serialization errors in the worker.  The reason is that the calculated serial 
version changes between the two.  Even if I manipulate/add a serialVersionUID 
to match technically these are going to be incompatible changes, as officially 
the type of some fields/parent classes will have changed.  Perhaps this is the 
best that we can do.

> Migrate APIs to org.apache.storm, but try to provide backwards compatability 
> as a bridge
