This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:
This error can occur when using Simulink without Java. To avoid this problem, do not use the -nojvm flag.
If you do not wish to use the MATLAB desktop, use the -nodesktop flag instead.
