资 源 简 介
COJAC is a tool performing On-the-fly code instrumentation to help uncover numerical problems with integer (overflows) and floating point (smearing, cancellation, infinity, NaN) arithmetic.
COJAC detects overflows and floating points numbers anomalies in Java code. You can apply it on your own code to detect vicious bugs that aren"t detected by the Java Virtual Machine. This tool defines a new JVM option, so that COJAC features apply seamlessly on any existing Java software. No source code modification, no recompilation, all is done on-the-fly at runtime.
See the [User Guide](http://code.google.com/p/cojac/wiki/CojacUserGuide) for a more detailed description or an example.
COJAC is offered (without warranty of course) in the hope it can be useful for educational purposes, as well as in the software industry. Any comment/feedback is welcome!
