> ScreenFopViewHandler.java:93, REC_CATCH_EXCEPTION
> - REC: Exception is caught when Exception is not thrown in org.apache.ofbiz.widget.renderer.fo.ScreenFopViewHandler.render(String, String, String, String, String, HttpServletRequest, HttpServletResponse)
> 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 ...
>   }
