It looks like anywhere you go in the Java blogosphere, people are only talking about Java 6 (or lack of thereof) on Leopard. Some say that the only reason they bought Leopard was for Java 6, some say that their honeymoon with Apple is over, and some say that Java 6 will be available shortly as a separate download. And 99% of the postings and the comments seem to agree – Java 6 should have been included in the golden master of Leopard.
I thought about it over the weekend, and time and time again i reach the same pragmatical conclusion – i don’t care about Java 6 on OS X, and for that matter i don’t care about OS X as a Java development platform. While that may sound as a harsh statement, allow me just a few minutes of your time.
I’ve already written that for me, an operating system is just another layer in my development platform. I’m more interested in the tools that i’m using and the applications that i’m developing. The things that i said 30 months ago are still true – i’m perfectly OK with my Windows machines, because i rarely directly interact with the operating system. I might have switched to Linux, but pragmatically speaking, it is not a good business proposition. Between 150$ for the OEM version of Vista and spending 12 hours to download and install OS and configuring the Java environment (on my free time during the weekend away from the family), i choose Vista any given day.
Now, let’s talk some numbers. The market share for Windows is somewhere in 90-95% range, and while sales of Mac machines rise on the quarterly basis, so do sales of Windows boxes. One might say that these numbers are for all the machines, including corporate environments and home machines for non-IT people. I’m looking at the visitor stats of this blog, which is has a very specific technical orientation, and the numbers are a little surpising:
- Windows has 75.6%
- Linux has 14.4%
- Mac has 9.6%
Yes, even for such a narrowly oriented site that mainly talks about Swing, Java2D and other UI topics in Java land, Mac doesn’t even cross into double digits. While you do see most of JavaOne presenters use Mac laptops, it doesn’t really extrapolate to the wider audience of JavaOne attendees, and most certainly it doesn’t extrapolate to the much wider audience of Java developers. The same applies to the blogosphere numbers – i’m sure i have seen about 20-30 rant entries on this subject over the past three days. Let’s be generous and say it’s an even hundred. Is that a lot? It is a lot of noise, but compared to the number of blogs tracked by JavaBlogs (2261) it’s not that much.
Looking at the bug reports for my open-source projects over the past three years, i see only two Linux-specific bugs and one Mac-specific bug. Yes, about 500 bugs reported via the bug trackers, forums, mailing lists and direct mail, and only one Mac-specific bug. Of course, most of these bugs were cross-platform, but so have been the bug fixes.
Now, your numbers might be different. If you’re developing a commercial product that is targeting multiple OSes, you might not be in a position similar to mine. However, if you spend more money to provide support for Mac than what you make from product sales on Mac, that is a bad business proposition. In this case, you might as well say that your product is for Windows only (like the vast majority of all the applications out there) and don’t mention that it’s in Java (so you don’t get blog-flamed about lack of cross-platform support). Of course, in this case you might as well switch to Win32, MFC, WinForms, WPF or whatever technology is pimped that year, but that is a topic for another blog entry.
This is, of course, my personal subjective opinion. I never had a Mac, and this fact alone might severely skew my judgement. But on the other hand, i never had to have a Mac as a Java developer. And this most certainly doesn’t change now with Leopard. Windows (in its various flavors) was and remains my only Java development platform (both at work and at home), with Linux and Mac delegated to what they really are at this point in time – alternative OSes with minor penetration to be installed for platform-specific bug fixes. Will this change in the future? I’m a pragmatic person, so i don’t say “no”.
