Some background: I currently make a living developing Java EE applications. My current project has over a quarter of a million lines of Java code, plus a ton of JSPs, SQL scripts and other supporting files. I use Eclipse as my IDE of choice since it has a lot of features to make developer's lives easier. Some of the best features are:
When I opened Fedora's native Eclipse I noticed my laptop became
slow and unresponsive, and the CPU usage skyrocketed to 100%.
My work project directory is called "workspace" and it is right under my home directory. This is the default project location Eclipse creates, native Eclipse went straight to this location every time I opened it, not remembering I had switched workspaces before, like normal Eclipse does.
After switching (again) to my personal projects workspace, I created a new Java project, and added the ubiquitous "Hello world" class, everything worked as expected. To make things a little more interesting, I added some code using generics, which is a new feature added in JDK 1.5, aka Java 5 and purposefully added some invalid code. Native Eclipse correctly flagged the invalid code.
I then proceeded to use Eclipse's auto complete feature to create a for loop iterating over the ArrayList, the generated code was not generics friendly, it used an iterator without using generics, and created a cast inside the loop.
For completeness' sake, I tried the same exercise under standard Eclipse and got the same result, therefore this behavior is not specific to native Eclipse.
After fixing the generated for loop to use generics, I saved the file and attempt to run the generated class file using the GNU Interpreter for Java (gij), I was gladly surprised that it worked without any problems. It was surprising to me since I have native Eclipse set up to generate Java 5 code, and I was under the impression that gij only understood JDK 1.4 and below code.
After I was done playing around with my simple hello world app, I opened another project I have in my personal workspace. This particular project has about 67,000 lines of code. Native Eclipse opened it without a hitch. I made some simple changes here and there, and found nothing out of the ordinary.
Is native Eclipse ready for prime time? I believe that for all but the largest projects it is. It is now feasable to develop Java applications using nothing but Free/Open Source software, especially since the generated code is compatible with gij.
