In crash reports, the "CPU" is "bcw$7@<memory address>"


    • Icon: Bug Bug
    • Resolution: Fixed
    • Minecraft 1.9.4, Minecraft 16w21a, Minecraft 16w21b
    • None
    • Confirmed

      In the last line of a crash report, it shows your CPU. In 16w21a however, it shows a raw Java object and not a string:

      	CPU: bcw$7@74f1c9b9

      Here's a full crash report:
