Research direction

Start by reproducing classloader -l on Windows 11 with JDK 8, first in a small terminal and then after resizing or switching to full screen. Trace the classloader command's output rendering and verify that the hash and parent columns remain visible regardless of the terminal size; the issue is complete when the behavior is consistent with starting in full screen.
