Consider using a newer version of H2. You are using version 1.1.102
which is old and no longer supported.
I believe you are using a different database URL than the one you
posted. The error message says you didn't specify a file encryption
password, but this message can only appear if you use file encryption,
which you need to specify in the database URL (for example
jdbc:h2:file:~/workspace/ACServer/server_storage/acmdb;ACCESS_MODE_DATA=r;cipher=AES).
