Remediation

From Azure Portal

1. Log in to the Azure portal using https://portal.azure.com.
2. Go to App Services.
3. Select each app.
4. Under Settings section, click on Configuration.
5. Select 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 {{number-of-workers}} \
    --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.
