Wrappers do not raise system errors

[jasper]

C++ code can raise a cape_open_error, which is is translated by interface wrappers to returning a CAPE-OPEN error code and storing the internal error.

Here the generated error code is always COBIAErr_CAPEOPEN_error despite system error codes being used to construct the cape_open_error

Applies to code generator and client header files (which are code generated)
