Note: Make sure the api rest endpoints are same as the ones we using the spring version so that the web app will be functional for both of them. If they are different in th eolder version, change them to match the current spring version.

Endpoint - /micro/items

We have this issue https://github.com/OpenLiberty/open-liberty/issues/11582 here. There was a problem like this before and the fix is released for the openliberty version 20.0.0.5 but the current stack is using openliberty version 20.0.0.3

I checked with one of the devs working on stacks and they have a PR ready for updated version pointing to 20.0.0.6 and mentioned that they will be updating it in next couple of days. They suggested us to re-build if needed.

@csantanapr do we want to wait on them for the fix or go ahead and build a local stack to make things work ?

[csantanapr]

Let's build our own and push it to DockerHub for now

Past experience they take for ever to pick updates on stacks.
