Strange errors after upgrading to Camunda 7.3 alpha. Application cannot be deployed.

[Emerald Hieu]

Hi, 

Today I tried to upgrade to Camunda 7.3 alpha. The steps I did:

1) Run the "upgrade" script for process engine database.

2) Change the datasources in standalone.xml for my application.

3) Change JBOSS_HOME to new version's directory.

4) Update Camunda version in my application's "pom.xml".

5) Upgrade Eclipse Modeler to the latest.

6) Start the server.

I get this error when starting the server.
