In my quick scan of the previous PR builds (https://dev.azure.com/eclipse-omr/omr/_build?definitionId=1&_a=summary), I found that the failure is also seen in #7046. fyi @hzongaro @jdmpapin

In a build I found where that test passed, I see this:

7: Working Directory: /Users/runner/work/1/s/build/jitbuilder/release
27: Test timeout computed to be: 10000000
2: ................................................................................................../Users/runner/work/1/s/jitbuilder/apigen/test/cppgentests.py:245: DeprecationWarning: Please use assertRegex instead.

In the Azure pipeline, macOS-latest is used for the VM image, which probably has the latest Python version where assertRegexpMatches no longer exists. If JitBuilder has a specific Python version requirement, then it can be included in azure-pipelines.yml to resolve this issue. fyi @AdamBrousseau
