When using your solver from the command line, it prints...

1. the scrambled 5x5 state
2. the reduction moves
3. the reduced three by three state.

At least I think it's supposed to be the reduced 3x3 state based on the fact that all centers and wings are always paired. However, there seems to be a bug with printing because after executing the reduction moves, my real 5x5 does not match the reduced 3x3 state printed out by your program. Most notably, the reduced 5x5 that gets printed "always" (sample of N=20 random states) has all corners solved.

It seems to affect the printing only. The internal String representation itself is fine, because passing that internal state to min2phase produces a correct solution that will indeed solve the physical 5x5 I'm using to verify the solution.

Is this an actual issue or is the second 5x5 printout supposed to be something other than the reduced 3x3 state?

I ran into a null pointer exception while making a unit test , every time this happening attached statckstrace and facecube
