That is due to

> java.lang.NullPointerException
>         at net.adaptivebox.deps.behavior.PSGTBehavior.generateBehavior(PSGTBehavior.java:100)
>         at net.adaptivebox.deps.DEPSAgent.generatePoint(DEPSAgent.java:126)
>         at com.sun.star.comp.Calc.NLPSolver.DEPSSolverImpl.solve(DEPSSolverImpl.java:169)

which ultimately gets translated into a C++
com::sun::star::uno::RuntimeException (via a BridgeRuntimeError thrown from
Bridge::handle_java_exc, bridges/source/jni_uno/jni_uno2java.cxx, and then via
the C++ UNO bridge), thrown from within

>     xSolver->solve();

in ScOptSolverDlg::CallSolver (sc/source/ui/miscdlgs/optsolver.cxx), which
remains uncaught.
