Application fails to start because of java.lang.IllegalStateException: Configuration pid com.ibm.ws.app.manager_23 was deleted.

Describe the bug
While starting an OpenLiberty docker image with a dropin app in it, app start failed with the following issue:

    [ERROR   ] CWWKE0701E: FrameworkEvent ERROR java.lang.IllegalStateException: Configuration pid com.ibm.ws.app.manager_23 was deleted.
    	at com.ibm.ws.config.admin.internal.ExtendedConfigurationImpl.exceptionIfDeleted(ExtendedConfigurationImpl.java:666)
    	at [internal classes]
     Event:org.osgi.framework.FrameworkEvent[source=com.ibm.ws.config_1.0.34.cl191120191031-0300 [9]] 

Since this happened inside Docker in a TravisCI build I do not have further logs or FFDC.

Steps to Reproduce
Intermittent issue. Can attempt to reproduce by doing:

1. Clone the MicroShed Testing repo: https://github.com/MicroShed/microshed-testing
2. Run the test: ./gradlew :microshed-testing-liberty-app:test

Expected behavior
App should start successfully each time.

Diagnostic information:

• OpenLiberty Version: Open Liberty 19.0.0.11/wlp-1.0.34.cl191120191031-0300
• Java Version: Eclipse OpenJ9 VM, version 1.8.0_232-b09
• Docker image: openliberty/open-liberty:full-java8-openj9-ubi
• server.xml configuration:

<server>

    <featureManager>
        <feature>jaxrs-2.1</feature>
        <feature>jsonb-1.0</feature>
        <feature>mpHealth-2.0</feature>
        <feature>mpConfig-1.3</feature>
        <feature>mpRestClient-1.1</feature>
        <feature>beanValidation-2.0</feature>
        <feature>cdi-2.0</feature>
    </featureManager>

    <!-- no other config, dropin app is used -->
        
</server>

Additional context
Dockerfile is generated but equates to:

FROM openliberty/open-liberty:full-java8-openj9-ubi
COPY src/main/liberty/config /config/
RUN configure.sh
ADD build/libs/myservice.war /config/dropins
