Trying to run basic logback example with Jansi support; it fails because the Win32 call to GetConsoleScreenBufferInfo returns 0. MSDN docs state:

"If the function fails, the return value is zero. To get extended error information, call GetLastError."

The logged call to GetLastError returns "T h e o p e r a t i o n c o m p l e t e d s u c c e s s f u l l y ."

Odd.
