What about creating a patch file... We love contributions :)
                
> FileSystemBlobStrategy#getFile(ActiveMQBlobMessage) is not thread safe

>             Project: JAMES Server
>          Issue Type: Bug
>          Components: Queue
>    Affects Versions: 3.0-beta3

> IOException {
>         ...

> Suppose this method is called from two threads. If both threads get past the 
> condition
>         if (queueF.exists() == false),
> then the first one will create queueF. For the second, queueF.mkdirs() will 
> then return false, which leads to an IOException even though everything is 
> fine. I think the condition should be replaced by
>         if (!queueF.mkdirs() && !queueF.exists()).
