When using Version 1.47.0, the VS Code test runner does not properly load when opening a Java project. It instead says no tests found in the workplace and I get the below error in the output. Downgrading to 1.46.0 solves the issue.

When using Version 1.47.0, the VS Code test runner does not properly load when opening a Java project. It instead says no tests found in the workplace and I get the below error in the output. Downgrading to 1.46.0 solves the issue.
Expected behavior: Test runner shows tests
Actual behavior: Test runner says no tests found and prompts me to install testing extension.
Workaround: Downgrade to version 1.46.0
