Hello list,

I am using itext for tiff to pdf conversion. In doing this I sometimes
obtain the below error. In fact it happens very rarely (like once in a
million conversions). I am using iText version 5.0.1.

The line in my code that leads to this error is:
RandomAccessFileOrArray ra = new RandomAccessFileOrArray(filePath);

Also, this is document independent. When I run the conversion again on
the document for which it failed earlier, everything goes fine.

The process that does the conversions runs many threads, so this
RandomAccessFileOrArray constructor can be called by multiple threads at
the same time. 

So, looks like there is something not thread-safe. Should I have known
this or is this a bug?

Thanks for any advice,
dirk
