Thomas Koch updated ZOOKEEPER-1259:
-----------------------------------

    Attachment: ZOOKEEPER-1259.patch

The method SerializeUtils.deserializeTxn() did not have a switch case for the 
check txn. Since I only put txn types from this switch in the map, I forgot the 
check txn.

The failing cpp test did not have a counterpart in a java test, so I added a 
java test now.

Only thing is, that SerializeUtils.deserializeTxn() will not fail on a checktxn 
after this patch as it would have done before. But that seems to be a good 
thing?

> There are two places where large switch statements do nothing else to get the 
> correct Record class accorging to a txn type. Provided a static map in 
> SerializeUtils from type to Class<? extends Record> and a method to retrieve 
> a new txn Record instance for a type.
> Code size reduced by 28 lines.
