-----------------------------------

             Summary: NPE with ImageParser 2.1.0
                 Key: TIKA-3569
                 URL: https://issues.apache.org/jira/browse/TIKA-3569
             Project: Tika
          Issue Type: Bug
          Components: parser
    Affects Versions: 2.1.0
            Reporter: David Brosius
             Fix For: 2.1.1


Using ImageParser, i pass a png, to parse.. and i debug in and see in AbstractImageParser, 
```
String mediaTypeString = metadata.get(Metadata.CONTENT_TYPE);
 //note: mediaType can be null
 MediaType mediaType = normalizeMediaType(MediaType.parse(mediaTypeString));
 MediaType ocrMediaType = convertToOCRMediaType(mediaType);
 Parser ocrParser = EmbeddedDocumentUtil.getStatelessParser(context);
```
and indeed mediaType is null, as the comment forwarns.

but convertToOCRMediaType does
```
 static MediaType convertToOCRMediaType(MediaType mediaType) {
 return new MediaType(*mediaType*.getType(), OCR_MEDIATYPE_PREFIX + mediaType.getSubtype());
 }
```

which NPEs.
