----------------------------------------
Hi Simon:
OK I read through the thread on this -- your patch is a bit outdated against
the current MimeTypes.java in the current trunk. Also, I think a better way to
achieve what you'd like to do without breaking back compat with
getMimeType(byte []) is to simply add a new method (or alternatively create a
new Detector) that combines the functionality of hinting, and that of magic
detection, which is essentially what you implemented.
Beyond that, we should put together a unit test to demonstrate the behavior
you're seeing (100x calls to tika.detect returns diff results on the same XLS
file).
Thoughts?
Cheers,
Chris

>
> 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.
