There are no inner classes and I still can't set breakpoints. File in
question is attached.

/**
* This class implements the hazard physics model. It models blast effects,
* thermal radiation, and damage to structures given a specific yield.
*<P>
* The hazard calculation is done through a JNI call because most of the work
* is supported in FORTRAN and by people at Sandia National Labs. The file name
* attribute doubles as both the output file name and the library to load
* dynamically.
*<P>
* The following is an example of how to create an object using this class.
* This example generates two files: one called NukeModel.txt and the other
* NukeModel.dat. It also expects that there lives a library called
* NukeModel.so on Sun machines and NukeModel.dll on PC compatible machines.
