Steps to Reproduce
This is the same issue as #4946 for a different class, since there is also a JSON string comparison here. In summary, since JSONs are unordered, after converting them to strings, the parameter ordering is not guaranteed. For another example of this issue being addressed, see this previous merged PR.
This test was flagged via the NonDex tool, which detects potentially unreliable tests due to underlying Java API assumptions. To see the Nondex output for this test, you can run:
mvn -pl metrics/metrics-core edu.illinois:nondex-maven-plugin:2.1.7:nondex -Dtest="org.apache.servicecomb.metrics.core.publish.TestThreadPoolPublishModelFactory#createDefaultPublishModel"
Expected Behavior
The test should pass regardless of JSON parameter ordering, since it's just checking that the object was created with the right initial values.

Additional Context
I have a potential fix in a PR, I'll be adding that to the discussion.
