Understanding javax.net.ssl.SSLException in Java 11

Encountering exceptions while working with Java's HTTP client can be frustrating, particularly when migrating from older versions like Java 8 to Java 11. One common issue developers face is the javax.net.ssl.SSLException: closing inbound before receiving peer's close_notify. This typically occurs when dealing with HTTP responses and can lead to unexpected application behavior.

The Problem

In your case, the exception is thrown when trying to close the HTTP response, as shown in the following code snippet:

Analyzing the Cause

The error occurs due to the order of closing resources in your finally block. In Java 11, you need to ensure that resources are closed in the correct order to prevent this SSLException. It seems that Java 11's improved handling of SSL connections is stricter than that of previous versions.

The Solution

To resolve the SSLException and manage resource closure effectively, we can utilize a modern Java feature known as "try-with-resources." This feature automatically handles closing of resources when they go out of scope, significantly simplifying the code and reducing the chance of errors.

Implementing Try-With-Resources

Here’s how you can refactor your existing code to leverage try-with-resources:

Benefits of This Approach

Automatic Resource Management: You no longer need to explicitly close the response or the reader; the JVM will take care of closing them when exiting the try block.

Reduced Boilerplate Code: The try-with-resources syntax reduces the amount of code you have to write, making your code cleaner and easier to read.

Enhanced Error Handling: Since the resources are closed even if an exception is thrown, you mitigate the risk of resource leaks.

Conclusion

Dealing with SSL-related exceptions in Java can be challenging, especially when upgrading to newer versions. By adopting best practices such as the try-with-resources statement, you can effectively avoid common pitfalls and ensure the smooth functioning of your applications. Once you implement this change, you should be able to close your HTTP responses without encountering the javax.net.ssl.SSLException.
