Java testing/memory tools

While a newbie at java, I've been assigned at work to help test some tools for our development work in java. We're looking at NuMega tools (TrueTime, TrueCoverage, and JCheck) as well as OptimizeIt.
I've been looking mostly at NuMega stuff recently. It lets you run your application under the tool, do whatever, then exit and save the tool's results as a 'session'. After that, you can study what the tool found out. TrueTime studies execution times for methods, including the entire tree of parents and children. A cool feature is that it lets you drill down from high level to low, right down to code. JCheck does the same for memory, TrueCoverage for testing code.
OptimizeIt doesn't have the drill down features, but it isn't session based. It lets you study memory usage in real time as the application runs, with graphs and charts.
I hear Jtest (from www.paragon.com) is a tool for testing how good your code is. Sort of like a style guide, but much more. Does anyone know anything about this tool?

Are you saying that JTest is like lint for Java?

There is a product review on the latest version of jtest in the January issue of Java Report.
It claims jtest can perform Black-Box, Regression, and White-Box testing as well as the style checking and standards enforcing as discussed.

I've used jtest! quite a bit and it is as advertised. Very thorough. It's about $3000 a seat and node locked to your IP address. Let's you know of any possible uncaught exceoptions in your code (which is a hassle sometimes as it puts a null in for every value and spits out possible null pointer exceptions, even when you know programatically it is almost impossible to get a null there). It's worth a demo. Parasoft gives like a 48 hour demo of the product and it only reports the first 3 exceptions of each type per source file etc. Check it out from the web site.
 
I agree. Here's the link: http://aspose.com/file-tools
