org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoSuchFieldError: INSTANCE

[sbmaggarwal]

I have following Maven dependency in my Java Spring Boot project:

<dependency>
    <groupId>com.cloudinary</groupId>
    <artifactId>cloudinary-http44</artifactId>
    <version>1.17.0</version>
</dependency>

The following issue happens even if I switch to 1.18.0 or 1.19.0 for cloudinary. As soon as I try to upload a new file with Cloudinary object with following code:

Map uploadResult = cloudinary.uploader().upload(file.getBytes(), params);

I get the following error:

org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoSuchFieldError: INSTANCE
	at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:982)

When I hit the same request again, the error I get:

org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class org.apache.http.conn.ssl.SSLConnectionSocketFactory

I tried adding Http Client and core dependencies at top of maven dependency list but no resolution:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpcore</artifactId>
    <version>4.3.3</version>
</dependency>

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.1</version>
</dependency>

With the following code, I tried to find out where the class SSLConnectionSocketFactory is:

ClassLoader classLoader = StorageService.class.getClassLoader();
URL resource = classLoader.getResource("org/apache/http/conn/ssl/SSLConnectionSocketFactory.class");
log.info("Resource: {}", resource);

I see the following response in logs:

Resource: jar:file:/Users/shubham/.m2/repository/org/apache/httpcomponents/httpclient/4.5.3/httpclient-4.5.3.jar!/org/apache/http/conn/ssl/SSLConnectionSocketFactory.class

What should I do?

Hi @sbmaggarwal , I'm sorry for the late response. looks like a dependency conflict, could you please share the pom file so we can try and figure it out? Thanks, Yakir
