REC: Exception is caught when Exception is not thrown (REC_CATCH_EXCEPTION)

  This method uses a try-catch block that catches Exception objects, but Exception is not
  thrown within the try block, and RuntimeException is not explicitly caught.  It is a common bug pattern to
  say try { ... } catch (Exception e) { something } as a shorthand for catching a number of types of exception
  each of whose catch blocks is identical, but this construct also accidentally catches RuntimeException as well,
  masking potential bugs.
  
  
A better approach is to either explicitly catch the specific exceptions that are thrown,
  or to explicitly catch RuntimeException exception, rethrow it, and then catch all non-Runtime Exceptions, as shown below:
  
  try {
    ...
  } catch (RuntimeException e) {
    throw e;
  } catch (Exception e) {
    ... deal with all non-runtime exceptions ...
  }
