VSCode fails to load Java Project if a config class with same name exists in test directory

My project structure is like this
src
main
java
config
MongoConfig
test
java
config
MongoConfig -- Disable transactions in test profile

Environment

• Operating System: Windows 10
• JDK version: 11
• Visual Studio Code version: 1.67.2
• Java extension version: v1.6.0

Steps To Reproduce

1. Create a Spring Project
2. Add a Spring configuration with name MongoConfig with any contents
3. Copy the same config to test folder
4. VSCode will fail

[Please attach a sample project reproducing the error]

Current Result

VSCode fails to load the Java Project

Expected Result

VSCode should not validate classes with same names

Additional Informations

Below is the error from the Java Server log

Reproduce the failure with duplicate MongoConfig classes in the main and test Java directories, then trace the diagnostic conversion in WorkspaceDiagnosticsHandler and JsonRpcHelpers using the reported stack trace. Done means the Java project loads without the BadLocationException or NullPointerException when same-named classes are present.
