I'm not sure what would cause that stack trace.
The inner most exception:
>Caused by: java.lang.NullPointerException
> at
> ptolemy.domains.ct.kernel.ODESolver._makeSolverOf(ODESolver.java:246)
does not match the beta source code, line 246 is not in _makeSolverOf().
1. What platform are you running under?
2. What version of Java are you using?
3. Are you using the prebuilt Windows version of Ptolemy or did you
download the sources and rebuild?
4. Has ptolemy/domains/ct/kernel/ODESolver.java been modified?
The version I have looks like:
