In the following example, a catch block is used to add an entry to an error log before re-throwing the exception.

It is possible to use a single try...finally block even when dealing with multiple resources, but that requires a correct use of sentinel values, which is another common source of bugs By default, the report method simply passes the exception to the base class where the exception is logged. So all other things being equal, if you can eliminate conditionals / conditional statements from your code, you will likely have more robust code.
