String parameters enclosed in quotes in activity functions

We are experiencing the issue described in azure-functions-durable-extension/issues/2674 in Java activity functions.

Our existing durable function orchestration started failing out of the blue. No changes were made to the code base or dependencies of our service using durable Java functions. The service works (for now) on a linux app service plan in Azure but fails on Windows with the latest Core Tools. String parameters are enclosed in quotes in any activity functions. Using the example capitalize cities workflow from the official docs demonstrates the issue. Output below:

{
    "name": "Cities",
    "instanceId": "47f91af6-e5f0-4ea1-a363-f6d00ca812c2",
    "runtimeStatus": "Completed",
    "input": null,
    "customStatus": "",
    "output": "\"TOKYO\", \"LONDON\", \"SEATTLE\", \"AUSTIN\"",
    "createdTime": "2024-03-07T17:16:49Z",
    "lastUpdatedTime": "2024-03-07T17:16:51Z"
}

Comienza con endtoendtests/src/main/java/com/functions/AzureFunctions.java y reproduce el flujo de trabajo „capitalize cities“ en Windows usando las últimas Core Tools. Compara la salida de la actividad con el issue vinculado de azure-functions-durable-extension; se considera terminado cuando los parámetros de tipo string ya no se devuelven entre comillas envolventes.
