[EDIT]

This problem is a duplicate of this: https://community.liferay.com/forums/-/message_boards/message/101467403

The first run of the db-upgrade tool failed because the database could not be found. The db-upgrade.sh tool generated a wrong jdbc connection URL. Some slash was missing. I had to edit the portal-upgrade-database.properties file manually.

Now the upgrade does not work anymore and I get the stacktrace above ^^

I am using a Maria Db.

I also noticed that the upgrade tool is using the MariaDbDialect while the liferay portal, which is using the exactly same connection URL is using the MySQLDialect.  This looks suspicious to me as well.

[EDIT]

I deleted the liferay/osgi folder, even I changed nothing within this directory except of the configuration and replaced it with the original one and now the upgrade works.

[EDIT]

After the update was successful and the server also started successfully I receive the following exception with every page I try to access

I rolled back everything to 6.2 GA4 (since GA5 and GA6 are buggy) and tried the upgrade to 7.1. again.

I get several error messages during the upgrade simlar like this one:

2018-07-10 10:54:01.388 WARN&nbsp; [main][UpgradeProcess:443] Attempting to upgrade table Counter by recreating the table due to: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the r<br> ight syntax to use near 'PRIMARY on Counter' at line 1_Query is:_drop index PRIMARY on Counter [Sanitized]

These error messages did not occur when I upgraded from 6.2 GA4 to 7.0 GA7 and they also did not occur when I upgraded from 7.0 GA7 to 7.1 GA1.

After starting the server i received the same NullPointerException as above ^ with every page I try to access.

Since the updated worked for 6.2 -> 7.0 GA7 and only now when updating to 7.1. GA1 these problems occur, I assume something is wrong with the upgrade process.

(at least for the Mariadb. I am running mysqld  Ver 10.0.35-MariaDB for Linux on x86_64 (SLE 12 SP1 package)).
