Tika - Out Of memory Exception

Question

I have been working on Tika to extract text contents only from various files. I found a peculiar issue when I was parsing a doc file with images inside. The Image fetcher was called and it threw java.lang.OutOfMemoryError: Java heap space .

I was trying the same in tika-app 1.22 gui and was getting the following exceptions:

My questions are:

1. Why would I need to fetch the image for text only extraction from documents?
2. How do I configure Tika to skip fetching images like in this case. I don't wish to increase my heap memory to solve this instead gracefully skip the images.

Edit: I am reading a file as stream and wrapped it as tikaInputStream and then opened an outputStream to write the result in another file.

        outputWriter = new OutputStreamWriter(outputStream);
        WriteOutContentHandler writeOutContentHandler = new WriteOutContentHandler(outputWriter, writeLimit);

        AutoDetectParser parser = new AutoDetectParser();  
        Metadata metadata = new Metadata();

        parser.parse(inputStream, writeOutContentHandler, metadata);

I have attached the file which I used for testing and got the following exception:
