Overly broad 'throws' clause

Warning
New
Last modified: 03 December 2024

Reports throws clauses with exceptions that are more generic than the exceptions that the method actually throws.

Example:

After the quick-fix is applied:

Configure the inspection:

  • Use the Maximum number of hidden exceptions to warn field to ignore exceptions, that hide a larger number of other exceptions than specified.

  • Use the Only warn on RuntimeException, Exception, Error or Throwable option to have this inspection warn only on the most generic exceptions.

  • Use the Ignore exceptions declared on methods overriding a library method option to ignore overly broad throws clauses in methods that override a library method.

  • Use the Ignore exceptions which hide others but are themselves thrown option to ignore any exceptions that hide other exceptions but still may be thrown from the method body and thus are technically not overly broad.
