Update Azure Pipeline to Test Recent JDKs

[radamson]

Making updates to the Azure Pipeline so that it tests PRs against multiple JDK Versions. I haven't used Azure Pipelines before, so there might be a better way to do this.

Currently, it doesn't appear that Azure Pipelines support a cross-product matrix strategy like GitHub Actions, but there are some examples of how to replicate the functionality in Azure Pipelines.

fhir-validator-wrapper/41 highlighted a suspected issue that only appeared when using JDK 8 (relevant zulip thread).

Should we add JDK 17 support? It's the most recent LTS version of Java.

[markiantorno]

add it in, yes

[radamson]

JDK 17 appears to work with macos and windows, but ubuntu reported Failed to find the specified JDK version.

[radamson]

Do we want to add this back in? If so should it be set to 6?

[markiantorno]

these appear to be covered in the imageName bracketed arguments above? is that not the case?

[radamson]

Sorry I meant maxParallel specifically. The imageNames are covered.

Without maxParallel more than 3 jobs will run simultaneously. As I type 7 of the 9 jobs are running (2 have already failed)

[radamson]

@markiantorno any other changes you'd like to see in this PR?

[dotasek]

@radamson I invested some time in repairing the failing builds in Java 8 and 17 and then used the approach from this PR to create a new one: #653

I will leave this PR open for a response and then close.

[radamson]

@dotasek thanks for making those fixes/updates? It looks like there isn't a more recent PR where I can see the checks in GitHub, but I can see them happening in Azure Pipelines for your PR. I think the matrix approach I took was overkill now that I see what your config looks like 😅.

Once a new release is out I'll test to see if any of the fixes you implemented address the issue that originally brought this to light. details here and in the zulip thread linked, but TL;DR is that the profiles fetched when loading an IG with the validator varied by JDK version.
