How does the code look like in your case?

We delegate the test item search to upstream:

org.eclipse.jdt.internal.junit.launcher.JUnit5TestFinder.findTestsInContainer(JUnit5TestFinder.java:216)

@jdneo This seems to be a issue with Lombok library, I have reported a issue to both Lombok and JDTLS to handle it. SO closing this.
