Description of problem:

Business central isn't deployed when there was previously deployed a project with kmodule.xml, which has set session as default.

This is my kmodule.xml:
<kmodule xmlns="http://jboss.org/kie/6.0.0/kmodule" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<kbase name="remotekbase" default="true" eventProcessingMode="stream" equalsBehavior="identity">
<ksession name="session" type="stateful" default="true" clockType="realtime" scope="javax.enterprise.context.ApplicationScoped" />
</kbase>
</kmodule>

Below are the exceptions during BPMS startup.
