Detector results for Excel formats

[Simon Tyler]

Hi,

I am doing some testing of Tika 0.6 and noticed some odd results for the
testEXCEL.xls file included in the test suite.

100 calls to the following code:

             is = new BufferedInputStream(new FileInputStream(filename));

            Metadata metadata = new Metadata();
            metadata.set(Metadata.RESOURCE_NAME_KEY, filename);
       
            String type = tika.detect(is, metadata);

Results in different matches as application/msword or
application/vnd.ms-excel seemingly at random.

Is this expected? Is there a way to mitigate it?
