Java version of TesseractOCRParser
URL: https://github.com/apache/tika/pull/158#issuecomment-493919876
Hello, I now use the tess4j API to identify images in Tika, and there is no
problem when I only deal with images, but I have a problem when I deal with
word file, because there are embedded images in the word file, and the error
information is as follows:
`

I have checked in two ways , first by using maven repository i.e
<!--
https://mvnrepository.com/artifact/com.github.jai-imageio/jai-imageio-core -->
<dependency>
<groupId>com.github.jai-imageio</groupId>
<artifactId>jai-imageio-core</artifactId>
<version>1.4.0</version>
</dependency>
Secondly , I have also checked by including the jar i.e
jai-imageio-core-1.4.0.jar
In both ways I am getting the same error , how can I fix this?
