I created a junit with the code from https://github.com/Azure-Samples/azure-cosmos-java-sql-api-samples/blob/fb3cee8e3d8faa69d97f6a61d4bf0633992426d0/src/main/java/com/azure/cosmos/examples/changefeed/SampleChangeFeedProcessorForAllVersionsAndDeletesMode.java but when I run it with Cosmos DB emulator, I don't received messages with ChangeFeedProcessor and handleAllVersionsAndDeletesChanges. I'm using the latest docker image version for the emulator : ``mcr.microsoft.com/cosmosdb/linux/azure-cosmos-emulator:latest`` I created a project to reproduce the issue. I have few tests src/test/java/com/example/demoredis/**CosmosDBTests.java** (with .handleChanges and it works) src/test/java/com/example/demoredis/**CosmosDBFeed3Tests.java** : SampleChangeFeedProcessorForAllVersionsAndDeletesMode (doesn't work) here the logs for **CosmosDBFeed3Tests** ```` [debug.log](https://github.com/Azure/azure-cosmos-db-emulator-docker/files/10297050/debug.log) ```` here my source code [demo-cosmos-feed-update.zip](https://github.com/Azure/azure-cosmos-db-emulator-docker/files/10297053/demo-cosmos-feed-update.zip)
