Console Import after Export returns a ClassCastException: Hi,
I have an _inmem database created as "in-memory db".
>From console I can connect to such db, by using:
> connect remote://localhost:2480/-inmem root
> Enter password: [aPwd]
> Connecting to database [remote://localhost:2480/_inmem] with user
'root'...OK
DISTRIBUTED CONFIGURATION:
{
"localName": "_hzInstance_1_orientdb",
"localId": "89a3db81-2daa-4878-9ef4-dec91259bceb",
"members": [{

}
Then I successfully create a couple of my classes and export the db from
the console CLI:

BUT when I try to import from the exported .gz archive, from the console
CLI (non-merge mode):

I get the fiollowing Exception (see below):
