Extension doesn’t play well with `@ParameterizedClass`

When using JUnit 5’s @ParameterizedClass, tests are executed but the Java Unit Test extension in VS Code always reports them as "No Result", regardless of whether they pass or fail.

The same tests report results correctly when run via Gradle or in other IDEs.

Environment

VS Code version: 1.107.1
Java Unit Test extension version: 0.43.2
Java version: 21
Build tool: Gradle
JUnit version: 5.14.1
OS: Windows

Reproduction Steps

1. Create a JUnit 5 test using @ParameterizedClass
2. Open the project in VS Code
3. Run the test using the Test Explorer or inline Run Test action

Minimal Reproducible Example

@Nested
@ParameterizedClass
@ValueSource(strings = { " hello ", "\tWorld\n", "JUnit  " })
class GivenUntrimmedString {

	@Parameter
	String input;

	@Nested
	class WhenNormalizing {

		String normalized;

		@BeforeEach
		void act() {
			normalized = input.trim().toLowerCase();
		}

		@Test
		void thenLeadingWhitespaceIsRemoved() {
			assertFalse(normalized.startsWith(" "));
		}

		@Test
		void thenTrailingWhitespaceIsRemoved() {
			assertFalse(normalized.endsWith(" "));
		}

		@Test
		void thenStringIsLowercased() {
			assertEquals(normalized, normalized.toLowerCase());
		}
	}
}

Expected Behavior

• Tests are executed once per parameter value
• Each execution reports a pass or fail
• Test Explorer shows the correct result status

Actual Behavior

• Tests are executed (side effects and logs confirm execution)
• Test Explorer shows "No Result" for the tests
• Status does not change even if assertions fail

Additional Notes

• This behavior appears specific to @ParameterizedClass
• @ParameterizedTest works correctly
• Nested tests without parameterized classes work correctly
• Command-line execution via Gradle reports results correctly

Start by running the supplied nested @ParameterizedClass reproduction through Test Explorer and the inline Run Test action, then trace the extension's result handling for those entry points. Done means each parameterized execution appears as pass or fail, including failures, while existing @ParameterizedTest and nested tests remain correct.
