The following are guiding principles we try to follow: This definition is a lofty goal and there is some practical limitation to how fully we can specify the API.

This may include assertions in the doc comments plus those in any architectural and functional specifications (usually written in FrameMaker) or in any other document. Ideally, the Java API Specification comprises all assertions required to do a clean-room implementation of the Java Platform for 'write once, run anywhere' - such that any Java applet or application will run the same on any implementation. This is why developers often need to turn to other documents, such as Java SE Technical Documentation and The Java Tutorials for programming guides. A staff with generous resources can afford to blend both into the same documentation (properly 'chunked') however, our priorities dictate that we give prime focus to writing API specifications in doc comments. These two targets are described in the following sections. Thus, there are commonly two different ways to write doc comments - as API specifications, or as programming guide documentation. We spend time and effort focused on specifying boundary conditions, argument ranges and corner cases rather than defining common programming terms, writing conceptual overviews, and including examples for developers. To this end, our target audience is those who write Java compatibility tests, or conform or re-implement the Java platform, in addition to developers. Our documentation comments define the official Java Platform API Specification.

This article shows the most common issues you may face using Lombok with JPA entities.

This is why we introduced a number of code inspections for Lombok to JPA Buddy. Analyzing the projects, we see people stumble into the same pitfalls over and over again. It is absolutely fine to use Lombok in your JPA projects, but it has some caveats.

Turns out, a lot of them use Lombok for their entities. Before writing a single line of code for it, we went through a ton of projects on GitHub to understand how people work with JPA. We develop JPA Buddy – a plugin for IntelliJ IDEA designed to make the use of JPA easier.

In this article we’ll look at how the misuse of Lombok can hurt the performance of JPA applications or even crash them, and how to avoid that but still gain the benefits of using Lombok. However, there are a few things to consider when using it with JPA. Lombok is a great tool that makes your Java code concise and clean.
