Issue/Introduction

After upgrading CDA from 12.2.4 to 12.3.3, the DMTool was upgraded as well from 1.2.7 to 1.4.0

When launching the Deploy workflow it fails on [email protected] with the following error that seems to indicate an incompatibility between dmtools.jar and the customer java version:

 DMTool: Version: 1.4.0
        DMTool: Date: 2020-04-20 07:51

Environment

Release : 1.4.0

Component : PACKAGE DM 

Cause

The error was due to the usage of a Java distribution (IBM JVM 9) not supported by PCK.AUTOMIC_DM 1.4.0

Only Oracle Java 8 and Openjdk 11 version are supported with PCK.AUTOMIC_DM 1.4.0 as explained in the compatibility matrix:

Resolution

Install a supported Java version and add it in the Agent's user path so that it's used instead of the unsupported Java version.
