Java isn't fast. Now, I am not attempting to start a FlameWar. Java can actually perform very well, as fast as C code in many cases. However, especially for [GUI]'s, Java doesn't come out too well. Even on a 650MHz computer, many Java interfaces programmed with the standard Java windowing toolkits will be slow and unresponsive. Case in point: Sun's own Forte. This is now called [Sun][[tm] One Studio 4, but is a good case of an unresponsive system written in Java that seems to otherwise be very well designed and implemented.
[Java] also has limitations due to it's [ClassFile] format
-Sun's JRE (run-time environment) is not [Free]-software (although it is [free] as in $$, and the source code is available). The "other" widely used JRE for [Linux] distributions, blackdown, is based on Sun's code, so therefore isn't Free either. Neither [Debian] or RedHat or many of the other distributions will officially distribute non-Free software.
The popular JREs start a new virtual machine for each java program, rather than sharing one amongst all programs. This combined with the large memory overhead can make it impractical on machines more than a few years old. (AddToMe - is this still true these days?)
-The lack of a Free JRE (along with JRE size and speed issues) is probably one of the biggest obstacles to wide-spread adoption of Java on Linux. However, most of the issues mentioned above are implementation issues so could in theory be overcome. For example, the [GCC] project is part-way through a java compiler that would (of course) be licensed under the [GPL].
