### AI overview

The article examines a malformed copyright comment in GPL-licensed Oracle code, where the year 2013 is repeated many times. It suggests the repetition may result from faulty code generation and questions the reliability of the surrounding file.

### Source excerpt

Today we have more of a representative comment, from Watson. This comes from some GPL licensed code published by everybody's favorite evil empire, Oracle. /* * Copyright (c) 2011, 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013 2013

### AI overview

The author argues that Oracle JDK for Java 11 has commercial-use restrictions and recommends choosing a free OpenJDK build for commercial use. The article cites Adoptium as a GPL-licensed option intended to provide more than four years of security patches.

### Source excerpt

TL:DR; Java is still available at zero-cost, you just need to stop using Oracle JDK and start using an OpenJDK build, such as this one or this one. The trap Java 11 has been released. It is a major release because it has long-term support (LTS). But Oracle have also set it up to be a trap (either deliberately or accidentally). For 23 years, developers have downloaded the JDK from Oracle and used it for $free. Type "JDK" into your favourite search engine, and the top link will be to an Oracle Java SE download page (I'm deliberately not providing a link). But that search and that link is now a trap. Oracle JDK, the one all web searches take you to, is now commercial not $free. The key part of the terms is as follows: You may not: use the Programs for any data processing or any commercial, production, or internal business purposes other than developing, testing, prototyping, and demonstrating your Application; The trap is as follows: Download Oracle JDK (because that is what you've always done, and it is what the web-search tells you) Use it in production (because you didn't realise the license changed) Get a nasty phone call from Oracle's license enforcement teams demanding lots of money In other words, Oracle can rely on inertia from Java developers to cause them to download the wrong (commercial) release of Java. Unless you read the text/warnings/legalese very carefully you might not even realise Oracle JDK is now commercial, and that you are therefore liable to pay Oracle for using this particular JDK in production. (Update, 2018-10-03: Searches for Java 11 and JDK 11 now seem to be resolving to OpenJDK builds, not commercial ones!) Is this trap malicious behaviour on the part of Oracle? Readers will have their own opinions. I do suggest bearing in mind that Oracle invests huge amounts in developing Java, so it is reasonable to have a commercial plan available for those that want it. And they do provide a $free alternative completely valid for commercial use... The

### AI overview

This article explains why Java users should consider OpenJDK builds beyond Oracle's JDK starting with Java 11. It describes how vendors produce builds from the OpenJDK source code, how TCK certification establishes Java SE compatibility, and how Oracle's JDK licensing and support differ from other builds.

### Source excerpt

From Java 11 its time to think beyond Oracle's JDK. Time to appreciate the depth of the ecosystem built on OpenJDK. Here is a list of some key OpenJDK builds. This is a quick follow up to my recent zero-cost Java post OpenJDK builds In practical terms, there is only one set of source code for the JDK. The source code is hosted in Mercurial at OpenJDK. Anyone can take that source code, produce a build and publish it on a URL. But there is a distinct certification process that should be used to ensure the build is valid. Certification is run by the Java Community Process, which provides a Technology Compatibility Kit (TCK, sometimes referred to as the JCK). If an organization produces an OpenJDK build that passes the TCK then that build can be described as "Java SE compatible". Note that the build cannot be referred to as "Java SE" without the vendor getting a commercial license from Oracle. For example, builds from AdoptOpenJDK that pass the TCK are not "Java SE", but "Java SE compatible" or "compatible with the Java SE specification". Note also that certification is currently on a trust-basis - the results are not submitted to the JCP/Oracle for checking and cannot be made public. See Volker's excellent comment for more details. To summarise, the OpenJDK + Vendor process turns one sourcebase into many different builds. In the process of turning the OpenJDK sourcebase into a build, the vendor may, or may not, add some additional branding or utilities, provided these do not prevent certification. For example, a vendor cannot add a new public method to an API, or a new language feature. Oracle JDK http://www.oracle.com/technetwork/java/javase/downloads/ From Java 11 this is a branded commercial build with paid-for support. It can be downloaded and used without cost only for development use. It cannot be used in production without paying Oracle (so it is a bit of a trap for the unwary). Oracle intends to provide full paid support until 2026 or later (details). Note that

### AI overview

The article argues that the GPL's ideological goal of preserving users' rights to modify and extend software also creates obligations for developers who reuse GPL-licensed code. It contends that the resulting source-disclosure burden can make developing a separate solution or choosing a more permissive license such as Apache or BSD more practical.

### Source excerpt

The thing that people need to keep in mind when discussing the GPL is that it was created to achieve an ideological and political goal, namely that users of software should have the right to modify and extend the software as they see fit. To achieve this goal, the GPL seeks to ensure that the source code is always available and that reusing the source code in question comes without any restrictions save for what the GPL itself imposes in order to ensure this "

The article explains common misunderstandings about intellectual property, focusing on how the GNU General Public License applies to free software and open-source projects. It discusses source-code access, GPLv2 and GPLv3 provisions, relicensing, and when software constitutes a derived work, with ReactOS as context.

### Source excerpt

Intellectual property is something way too many people like to talk about without actually understanding the nuances of the laws supporting them. While I could easily go on and on about these misconceptions, I'll focus primarily on those that relate to free software and open source, of which there are plenty. Some of the more prominent ones include incorrectly claiming what is and what is not a GNU Public License (GPL) violation and the notion that companies should "

### Source excerpt

I found this blog post about a couple Harvard students who wrote some [GPL'd] software for controlling worms' minds. They can control how these worms move and even make them lay eggs!The implications of this are obviously huge. This is only an academic project now, but in a couple decades I wonder if we'll see animals used like machines? I guess there's several other ideas you could draw from this, but no matter how you view it, it's a fascinating idea.
