Tika Document Reader issue (OpenAI and Mistral)

[kursatufukcoskun]

Bug description
Tika Document Reader dependency causing response type exception.

Environment
Spring Boot version: 3.3.4
Spring AI Version: 1.0.0-M2
Java Version: OpenJDK 22

Steps to reproduce
Add tika dependency to the pom.xml

<dependency>
     <groupId>org.springframework.ai</groupId>
     <artifactId>spring-ai-tika-document-reader</artifactId>
</dependency>

Call OpenAI chat model:

PromptTemplate promptTemplate = new PromptTemplate(getCapitalPrompt);
Prompt prompt = promptTemplate.create(Map.of("stateOrCountry", getCapitalRequest.stateOrCountry(),"format"  , format));
ChatResponse response = chatModel.call(prompt);
return parser.parse(response.getResult().getOutput().getContent());

Expected behavior
It should response as expected but when Tika dependency is in my project, cause response type exception.

Exception

By the way, this doesn't only happen with OpenAI. I tried it with Mistral, and it has the same problem. I didn't have this problem when I tried it with Bedrock. However, with Bedrock, the response is text, instead of json. When I remove the Tika dependency, the response turns into json again.

@kursatufukcoskun thanks for reporting this issue. I tried to reproduce the error, but couldn't do it. Perhaps could you share some more details about your setup or a small app example that reproduces the problem? Also, could you try and see if the problem is still there when using version 1.0.0-SNAPSHOT? Thanks!
