Remediation

From Azure Portal

1. Login to Azure Portal using https://portal.azure.com.
2. Go to App Services.
3. Click on each App.
4. Under Settings section, click on Configuration.
5. Click on the General settings pane and ensure that for a Stack of Java the Major Version and Minor Version reflect a currently supported release, and that the Java web server version is set to the auto-update option.

NOTE: No action is required if Java version is set to Off, as Java is not used by your web app.

From Azure CLI

To see the list of supported runtimes:

az webapp list-runtimes

To set a currently supported Java version for an existing app, run the following command:

az webapp config set --resource-group <RESOURCE_GROUP_NAME> --name <APP_NAME> --java-version <JAVA_VERSION> --java-container <JAVA_CONTAINER> --java-container-version <JAVA_CONTAINER_VERSION> --windows-fx-version <JAVA_RUNTIME_VERSION> --linux-fx-version <JAVA_RUNTIME_VERSION>

If creating a new application to use a currently supported version of Java, run the following commands. To create an app service plan:

az appservice plan create --resource-group <RESOURCE_GROUP_NAME> --name <PLAN_NAME> --location <LOCATION> --is-linux --number-of-workers <INT> --sku <PRICING_TIER> --hyper-v --sku <PRICING_TIER>

Get the app service plan ID:

az appservice plan list --query "[].{Name:name, ID:id, SKU:sku, Location:location}"

To create a new Java web application using the retrieved app service ID:

az webapp create --resource-group <RESOURCE_GROUP_NAME> --plan <APP_SERVICE_PLAN_ID> --name <app name> --linux-fx-version <JAVA_RUNTIME_VERSION> --windows-fx-version <JAVA_RUNTIME_VERSION>

From PowerShell

As of this writing, there is no way to update an existing application's SiteConfig or set a new application's SiteConfig settings during creation via PowerShell.
