org.springframework.web.client.RestClientException: Error while extracting response for type [org.springframework.ai.openai.api.OpenAiApi$ChatCompletion] and content type [application/json]

Bug description
When invoking a large model, the model requires a longer time for thinking, which leads to the disconnection of the network at the 60-second mark

Environment
spring-ai-bom 1.1.2
jdk17

Steps to reproduce
List list = deepSeekChatClient.prompt("获取小红书首页推送的笔记列表，获取前15条笔记的标题、封面图片地址、笔记详情地址")
.toolCallbacks(noteListTool)
.call()
.entity(new ParameterizedTypeReference<List>() {
});

After invoking the large model and then calling internal tools, the large model will think and output in a structured manner. The last step, where the model takes a long time to think, will result in an exception. Multiple tests have found that an exception occurs immediately if it takes more than 60 seconds
I have tried various configurations for underlying network requests, but none of them could solve the problem of reporting an error every 60 seconds
Expected behavior
I have tried various configurations for underlying network requests, but none of them could solve the problem of reporting an error every 60 seconds

Start at OpenAiApi.chatCompletionEntity and OpenAiChatModel.internalCall, then inspect the reported DefaultRestClient stack and reproduce the 60-second failure with the provided tool-calling example. Trace why the response ends with Premature EOF and establish behavior that allows the long-running request to complete without the reported exception.
