Sporadic failures in concurrent processing of PST files

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Get 2 PST files.
2. Create 2 threads, in each of them start processing a separate file
   - e.g. using readFolder().

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Reproducible on v0.7 - the latest one, I suppose?

Please provide any additional information below.

Well, I understand that enabling concurrent processing of a single PST file can 
be a lot of pain,
but concurrent processing of independent archives doesn't require that much of 
an effort. 
This particular issue can be fixed this way:

In com.pff.PSTTableItem:

Go to the line

    private static SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyyMMdd'T'HHmmss'Z'");

and remove "static" modifier:

    private SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyyMMdd'T'HHmmss'Z'");

You know, SimpleDateFormat isn't MT-safe.

I can even fix this myself, given write access.

Awesome, thanks for identifying this and fixing it, I've made your change in 
SVN and will attempt to get a new version released with this over the next few 
days.
