[jira] Assigned: (JS2-727) Appy Findbugs patches

Ate Douma reassigned JS2-727:
-----------------------------
Assignee: Ate Douma (was: David Sean Taylor)
> Appy Findbugs patches
> ---------------------
>
> Key: JS2-727
> URL: https://issues.apache.org/jira/browse/JS2-727
> Project: Jetspeed 2
> Issue Type: Bug
> Affects Versions: 2.1.1
> Reporter: David Sean Taylor
> Assignee: Ate Douma
> Fix For: 2.1.1
>
> Attachments: findbugPatch-comments.txt, findBugs.patch
>
>
> As reported by Dennis Dam on the mailing list, fix the "Findbugs" errors. I don't think we need a new issue for each bug, so Im listing all here:
> The other day I found a case in a particular class where an argument for a constructor was actually not used. I found that was really confusing. So I thought: is there not a way to find these kinds of "bugs" automatically?
> That's how I stumbled upon an open source (LGPL, I think) eclipse plugin which .. finds bugs for you! It's called 'findbugs' (http://findbugs.sourceforge.net/). Installation instructions are at http://findbugs.sourceforge.net/manual/eclipse.html.
> It works like this:
> - select project
> - select "find bugs"
> .. and off you go, it finds bugs. In the case of jetspeed it found 566 bugs to be exact, which it categorizes in degrees of seriousness. 73 are flagged as "high prio ". I attached these problems in a logfile attached to this mail. I would highly recommend installing that plugin from what I've seen so far.
> The nastiest bugs I found:
> - nullpointer dereference
> - possible infinite loop
> - comparing strings with the == operator
> These three are in the logfile.
> If anyone knows better plugins, or has suggestions I'm glad to hear about it.
