Description

When the Master receives a RPC call from any other version than 0.19, it gets:

2009-01-17 22:04:00,266 WARN org.apache.hadoop.ipc.HBaseServer: Out of Memory in server select
java.lang.OutOfMemoryError: Java heap space
        at org.apache.hadoop.hbase.ipc.HBaseRPC$Invocation.readFields(HBaseRPC.java:142)

        at org.apache.hadoop.hbase.ipc.HBaseServer$Listener.run(HBaseServer.java:308)

Easy to recreate by just starting a local 0.19 HBase and using the 0.18 shell to create a table.
