Trouble with the Liberty OpenAPI feature

[lmsurpre]

Describe the bug
During startup of the docker image, I'm seeing the following:

CWWKO1661E: An error occurred when processing application fhir-server-webapp and an OpenAPI document was not produced. The error was: java.lang.IllegalStateException: SROAP00001: Model already initialized.

Environment
main

To Reproduce
Steps to reproduce the behavior:

1. checkout main, build the project, build the docker image
2. docker run

Expected behavior
No errors during startup

Additional context
It doesn't prevent the server from starting but does seem to prevent the OpenAPI feature from working

Yep, I think thats it. I upgraded to Liberty 21.0.0.5 and the issue seems to have gone away.

This log message is no longer in the output and I confirmed that the openapi/ui endpoint is operational after startup, no further QA needed on this one.
