A potentially useful and cost-saving tool for Java developers
- Can save time
- There's a risk that sloppy programmers will misuse it
A potentially useful and cost-saving tool, if you're a programmer it's worth grabbing the 30-day trial of JavaRebel.
Price$ 149.00 (AUD)
Edit-compile-test-edit-compile-test. This is the "software development cycle" all programmers know well, from "Hello World" onwards. JavaRebel is a JAR file which will allow you to skip directly from "edit" to "test" while eliminating "compile" (most of the time).
Using JavaRebel is extremely simple: just pass an appropriate command when you invoke your Java Virtual Machine. It took us about 30 seconds to get it working in Eclipse. Once it's there, it's transparent - and useful.
To test JavaRebel, we launched an application, then, while the application was running, added in some additional output code to the event handler for a button.
After a second or two, we received a notice in our console window that the relevant classes had been reloaded, and the button now executed its modified behaviour.
We can foresee this saving a tremendous amount of debugging time. Even a few minutes a day saved re-launching apps adds up, over a year, to hours or even days of productivity, depending on re-deployment time after minor edits.
There are a few changes it can't handle - you can't change class hierarchy or implement new interfaces, for example, but it's unlikely you'd be making changes like that during a standard edit-compile-test cycle.
There is also a risk factor; if the app you're working on is "live" and you are careless with your configuration, you could introduce new bugs into running code. However, that's a user error and hardly the fault of the program.
The trial version of JavaRebel lasts for 30 days and prints a message in the console window when run. This should be long enough to determine if the utility provided is worth it.

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.
