Java: throw throws and Propagation

Swallowing exceptions, catching general exceptions, and incorrect stack traces.

A common pitfall is catching broad exceptions like 'Exception', making it harder to debug by hiding specific issues. Another is swallowing exceptions without logging, losing critical failure information. Incorrectly rethrowing exceptions can also lose the original stack trace. Ensure detailed logging and specific catches. For example, avoid 'catch (Exception e)' unless necessary.
