Hi Andy,

Since you asked . The right place to file bugs (the last 2 emails were bug reports), is our JIRA

https://jira.mariadb.org/projects/CONJ - for JDBC connector

https://jira.mariadb.org/projects/MDEV - for the server

You can write exactly the same content as you do here. You can also try stackoverflow,  but logically bug reports belong to the bug database.

Subject: [Maria-discuss] Problem updating to MariaDB java connector 2.6

I’m not sure if this is the right place to ask, so if not, please point me to the right place.

I have just tried updating the mariadb java connector from 2.5.4 to 2.6.1 and I get a Null pointer exception trying to open a connection. I am using the DriverManager.getConnection call which works with 2.5.4, but just swapping the jar file to 2.6.1 causes an exception (2.6.0 also has the problem). The exception traceback is shown below. I am using MariaDB 10.4.12 on Windows

Am I doing something wrong or is this a problem with 2.6.

Thanks for any help

Andy Ling
