Nobody has claimed this yet.

Issue Type: Bug

Steps to reproduce:

Open a maven project with TestNG tests (TestNG v. 7.6.1, surefire plugin v. 2.22.2).
Try to debug a test.

Expected behaviour:
Debugger hits a breakpoint in the body of test method.

Actual behaviour:
When I click on the Debug Test button, debug session does not start.
I see the following exeption in the debug console of VSCode:

Exception occured while running tests.

Reproduce the failure with a Maven TestNG project containing a test with dependsOnGroups, then start by reading TestNGListener.java around onFinish and the TestNGRunner entry shown in the stack trace. Confirm the fix by running the debug flow and verifying that it starts and reaches a breakpoint in the test method.
