I have downloaded the H2 console from http://www.h2database.com/html/download.html and I have configured the URL in my jdbc.properties file to jdbc:h2
jdbc.properties
jdbc:h2
Had the same Problem.
This solved it for me: Why is my embedded h2 program writing to a .mv.db file
Just added ;MV_STORE=FALSE and ;MVCC=FALSE to the jdbc url and everything worked just fine.
;MV_STORE=FALSE
;MVCC=FALSE
