Error messages - debugging suggestion

Issue description

First Im not sure this is the right place to Document this kind of issue, please direct me where to put it appropriately.

I copied some Java code (from D.Shiffmans Coding Challange #51) into Processing and tried to use error codes in order to amend it to processing code. The error codes are not accurate, even though I saw that they in version3 should better pinpoint the problem. Maybe this can be used for troubleshooting the Error Messages in order to improve them. At least for a beginner in processing such as myself it would be beneficial and less pain to start programming and translating form other sources.

Better error messages and reporting is something we've been working on for years and years... If you can point to a specific issue, please let us know. For example, a specific problem with the code that is reported inaccurately. The place to do that is over at processing/processing. This spot is for documentation: website, reference, examples, etc.
