I was trying to do some testing:

JanusGraph 0.2.2 can not read graph from 0.2.1.

org.janusgraph.core.JanusGraphException: StorageBackend version is incompatible with current JanusGraph version: storage [0.2.1] vs. runtime [0.2.2]

        at org.janusgraph.graphdb.configuration.GraphDatabaseConfiguration.<init>(GraphDatabaseConfiguration.java:1434)

I ended up replacing that check with the concept of the graph.storage-version when I wrote the upgrade for 0.3.x. Either we can hard code 0.2.2 as allowed or we can back-port the upgrade functionality. 

It really comes down to how many more releases are we planning to have for 0.2.x.

I should be able to submit a fix for this Monday if no one else grabs it.

Also, nice catch :)

I opened up Issue 1285 for the storage incompatibility of upgrade from 0.2.1 to 0.2.2. I will start a new voting thread for 0.2.2 when the release with a fix is ready.
