Overly broad 'catch' block

Reports catch blocks with parameters that are more generic than the exception thrown by the corresponding try block.

Example:

  try  {
    File file = new File(pathToFile);
    return file.getAbsolutePath();
  } catch (Exception ex) { // warning: 'catch' of 'Exception' is too broad, masking exceptions 'RuntimeException'
    return defaultFilePath;
  }

After the quick-fix is applied:

  try  {
    File file = new File(pathToFile);
    return file.getAbsolutePath();
  } catch (RuntimeException ex) {
    return defaultFilePath;
  }

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

TooBroadCatch

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | Java | Error handling

Configure the inspection:

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 which hide others but are themselves thrown option to ignore any exceptions that hide other exceptions but still may be thrown and thus are technically not overly broad.
