Environment:JDBC driver 2.2.1, MariaDB 10.1.30, Ubuntu 16.04 LTS
Description
If a database connection is tried when MariaDB server is down, the JDBC driver returns following error information:
Error code:-1
SQL State:08
Message:Could not connect to address=(host=localhost)(port=3306)(type=master) : Connection refused (Connection refused)
I believe error code -1 is not a valid error code and not documented at https://mariadb.com/kb/en/library/mariadb-error-codes/. Further, SQL State is expected to be 5 characters but not sure if it is right to return 2 character major class of errors.
Above mentioned error information can be reproduced by running attached program as following:
java MariaDbInvErrorCodeBug org.mariadb.jdbc.Driver jdbc:mariadb://localhost:3306/bladb blauser blapasswd
Output displayed by the program is as following:
Error code:-1
SQL State:08
Message:Could not connect to address=(host=localhost)(port=3306)(type=master) : Connection refused (Connection refused)
