For some reason I think I ran into this one myself once, it looks familiar.
Not 100% sure but I think it has a problem with 'initializing' the rocksdb.
Could you try something like this to see what happens: (just run it as sudo, but also make sure your directory is clean, in case there is some weird other db stuff happening)
mv iri-1.4.0.jar myIRI/
sudo java -jar iri-1.4.0.jar -p 14265
You might want to also use an ini file for your iri settings too. It might also help to tell iri where to have the DB_PATH (if just the above does't work, but also it's easier to use a config file in general).
To do that you can do this (the file you make, called "iota.ini" it's automatically picked up by IRI as the default name. You can read more about the config file on https://github.com/iotaledger/iri
#Now inside the iota.ini file put the following below to start...you will need to set your neighbors also on the NEIGHBORS line when you find some mutual ones.
PORT = 14265
UDP_RECEIVER_PORT = 14600
IXI_DIR = ixi
HEADLESS = true
DEBUG = true
TESTNET = false
DB_PATH = db
#Now save it with "Control + X", and then "Y"
See if any of that helps.
Note: If you use the iota.ini config file, you only need to run iri like this:
sudo java -jar iri-1.4.0.jar
Since it will use the port settings you define in the iota.ini file. If you name the config file anything other than "iota.ini", you would need to tell it you want to use a certain config file (ex: iri.ini)
sudo java -jar iri-1.4.0.jar -c iri.ini
