The PR at #122250 seems to have created a flaky test failure in
EsqlNodeSubclassTests. Local runs with-Dtests.iters=100lead to about two dozen failures in over 70k tests run. This is not a high failure rate, but still requires addressing.The single line added to the Analyzer by that PR causes an
UnsupportedOperationExceptionon attempting to mutate an immutable collection when runningEsqlNodeSubclassTests. It turns out that this code path comes fromRename.output()which is only called in test scenarios. So a quick fix is to copy the child output into a mutable collection.
