Reproduced again, when running test generation in a new IntelliJ project with newly installed JDK 17:

1. Plugin built from main installed in IDEA 2022.2.4
2. New IntelliJ project was created with JDK 17
3. Sample CastExamples was copy-pasted into the Sources root
4. Test generation was started with TestNG (not yet installed)
5. File -> Project structure was opened

Actual results:

1. Error popup was shown: "CastExamplesTest cannot be created."
2. IndexNotReadyException was thrown down to IDE immediately.

stacktrace is the same
