Rules are mapped to good and bad practices, as defined by the open-source community. They are computed by open-source rule-checking tools like PMD or FindBugs. They are classified by category associated to some quality characteristics.
Empty Catch Block ( EmptyCatchBlock ) provided by PMD Empty Rules 5.1.2
Empty Catch Block finds instances where an exception is caught, but nothing is done. In most circumstances, this swallows an exception which should either be acted on or reported.
This rule impacts reliability, since nothing is done about the exception and unpredictable behaviour may occur.
