SQL Server version

Client Operating System

Stock adoptopenjdk/openjdk11:alpine-jre image running on AKS

JAVA/JVM version

OpenJDK 11

Table schema

Problem description

1. Expected behaviour: Spring Boot on AKS can connect to Azure SQL using ActiveDirectoryServicePrincipal auth method
2. Actual behaviour: Client secret is null is thrown even when client secret is not null. Code works outside of AKS
3. Error message/stack trace: See trace logs below
4. Any other details that can be helpful: Code works normally outside of AKS in local JDK for example

Reproduction code

Running the sample JDBC code from the docs (https://docs.microsoft.com/en-us/sql/connect/jdbc/connecting-using-azure-active-directory-authentication?view=sql-server-ver15#connecting-using-activedirectoryserviceprincipal-authentication-mode) inside an AKS pod will also trigger the same problem
