Subject [jira] [Created] (TIKA-1166) FLVParser NullPointerException
Date Wed, 21 Aug 2013 16:44:51 GMT

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

             Summary: FLVParser NullPointerException
                 Key: TIKA-1166
                 URL: https://issues.apache.org/jira/browse/TIKA-1166
             Project: Tika
          Issue Type: Bug
          Components: parser
    Affects Versions: 1.4, 1.3, 1.2, 1.1
         Environment: All
            Reporter: david rapin


On certain video files, the FLV parser throws an NPE on line 242.

The piece of code causing this is the following:
https://github.com/apache/tika/blob/1.4/tika-parsers/src/main/java/org/apache/tika/parser/video/FLVParser.java#L242

241: for (Entry<String, Object> entry : extractedMetadata.entrySet()) {
242:   metadata.set(entry.getKey(), entry.getValue().toString());
243: }

Which should probably be replaced by something like this:

241: for (Entry<String, Object> entry : extractedMetadata.entrySet()) {
242:   if (entry.getValue() == null) continue;
243:   metadata.set(entry.getKey(), entry.getValue().toString());
244: }
