While testing the ALU, some of my students are experiencing issues with the HardwareSimulator crashing. One student is able to witness errors on the console, but is able to click the 'step' buttons repeatedly, and at some point the simulator takes off again and completes the test.

The hdl implementation is correct and passes the test. The Java error classes are:

Null Pointer Exception
java2d.NullSurfaceData

This is a preliminary problem report and I will provide more information once I can replicate the error.
