Description
The auto-generated business application zip file created once you click on the "Generate default business application" button fails to start up due to a H2 version which does not support some datasource properties defined in the autogenerated application.
Specifically, MVCC=true in H2 is no longer supported for the H2 version 1.4.200.
This H2 version comes bundled by default when using Spring-boot-starter-parent version 2.2.2-RELEASE.
As a workaround, customers will either have to remove this MVCC=true from the application.properties files from the autogenerated artifact or to downgrade the spring-boot-starter-parent version from the pom.xml.
Our supported current version of H2 in jBPM is 1.3.173
Another to keep in mind here is that the source code mentioned in the jbpm.org tutorial is pointing out to a completely outdated version of the autogenerated code mentioned above - https://docs.jboss.org/jbpm/release/7.37.0.Final/jbpm-docs/html_single/#_source_code_of_the_tutorial
