Bug Report
When running munit (scala) tests I'm getting a lot of warnings like these:
[dd.trace 2025-02-24 16:19:32:097 +0000] [io-compute-0] WARN datadog.trace.instrumentation.junit4.JUnit4Utils - Could not get test method
java.lang.NoSuchMethodException: com.example.Test.Name of test()

I guess because munit tests don't correspond to actual methods.
The test result seems visible in datadog.
Expected Behavior
No warnings.
Reproduction Code
package com.example
import munit.CatsEffectSuite
class Test extends CatsEffectSuite {
test("Name of test") {}
}
