Overview

Improved error handling in the multithreaded flatfile read integration test by adding proper exception propagation from worker threads to the main test thread. The FlatfileRead class now captures any exceptions that occur during execution in a volatile error field, which is checked after thread completion. This ensures that test failures in worker threads are properly reported rather than being silently ignored. Additionally, removed unnecessary exception printing and cleaned up unused imports.
