Asked 4 years, 3 months ago. Active 4 years ago. Viewed 12k times. I have installed El Capitan on my Mac, and whenever the mac boots, this screen appears.

Fiji now uses ImageJ2 at its core.

To use the "java" command-line tool you need to install a JDK. El Capitan OS X FIX

Most importantly, all involved developers are strongly dedicated to avoiding divergence—we are working closely together to ensure that ImageJ2 represents a continuation of ImageJ and Fiji, rather than a project fork. Fiji and ImageJ2 are fundamentally the same software, using the same launcher. So from the standpoint of development effort, the ImageJ2 and Fiji projects have indeed merged. ImageJ2 is the core software, and several pieces of infrastructure originally developed for Fiji have now migrated to ImageJ2 e.

At heart, Fiji is just a big collection of life sciences plugins though "Fijabcolsp" doesn't have quite the same ring to it. In other words, Fiji is just an ImageJ update site "Fijaius" —and as such, you can obtain a working Fiji installation by downloading ImageJ2, running the updater, and enabling the Fiji update site. All of that said, we do not want to get rid of the two distinct project names, since people are familiar with both.

But we are integrating resources when feasible: e. But we want to ensure it is clear that ImageJ is not a life-sciences-specific project, whereas Fiji is.

Historically, because Fiji has a life sciences focus, there have been some users who refused to switch from vanilla ImageJ1 to Fiji even though Fiji makes users' lives easier in lots of ways. With ImageJ2, we want to avoid such misconceptions. More effort is still needed to clarify web resources, to explain concisely and clearly where people should go in different circumstances. We also have plans to make bug reporting simpler and easier across the projects.

The Fiji's Menu page is especially helpful as it includes links to all the menu commands that ship as part of Fiji.

If you have an issue that is not mentioned here, you might want to ask on one of the mailing lists, or via IRC , or enter a bug report. While private mail might seem more desirable sometimes, but it is almost always inferior to the open process we established in ImageJ.

For starters, bug reporters are unlikely to know who would be the best person to address the issue. ImageJ is an Open Source community project.

The list of contributors is large but most of the people involved are not paid to work on it. We greatly value community contributions and assistance. There are not many professional developers whose formal jobs include responding to and addressing bug reports. These developers are not paid solely to fix bugs—rather, they are working to solve scientific problems and to advance the software's capabilities. The organizations above total over source code repositories, many of which have dozens of open issues in their issue trackers. There are also several hundred tickets in the old ImageJ issue tracker that are pending migration to GitHub Issues, as well as over a hundred open issues in the Fiji Bugzilla.

So please understand that just because we have not responded to a bug report, does not mean we are uninterested in fixing it. It's just that we are very busy, and can use all the help we can get! See the bug reporting best practices article for details. Java is one of the most popular programming languages and still one of the top choices for high-performance, cross-platform applications. Oracle is unlikely to attempt to "kill" Java, but even if they tried they probably couldn't—OpenJDK is open source and there is a massive community of Java developers behind it.

Java's popularity will eventually wane, but not because of any company's actions now. Rather, as with any programming language, new technologies will emerge and gain popularity, over a course of many years. For the time being, to avoid abandoning older machines which cannot be upgraded from Snow Leopard, ImageJ continues to target Java 6. Furthermore, updating the required version to a newer version of Java would necessitate improvements to the ImageJ Updater such that it could also update the bundled version of Java, which would be a substantial undertaking.

Otherwise, most existing installations of ImageJ would stop working, and those users would need to download ImageJ from scratch again. See this mailing list thread for further details. See the Philosophy page! While a pure web version of ImageJ would be desirable for a number of reasons, there are several substantial challenges with current technology. In particular, it would be difficult for a Javascript-based ImageJ to maintain compatibility with existing plugins, macros and scripts. For now, our goal is to continue improving the Java version of ImageJ, while remaining cognizant of developments in the web applications domain, to reduce the difficulties of a web version at some future date.

We are developing ImageJ with a careful eye toward modularity, avoiding gratuitous dependencies—particularly on AWT, which is not available on most mobile devices. We hope this approach makes it easier to port ImageJ to additional platforms in the future. A shorter term pragmatic solution would be an ImageJ web client that connects to a remote server running ImageJ in headless mode, which does the heavy lifting.

Java is still free and open source. The only reason to pay Oracle for a Java license is to continue receiving commercial support from Oracle after January for the Oracle version of Java 8.
