Errore di compilazione Java 8 quine (12203 byte)
Generato su windows + mingw con java 1.8.0_11 jdk, usando questo comando:
echo a > Q.java; while true; do javac Q.java 2> Q.err; if [ $(diff Q.err Q.java | wc -c) -eq 0 ]; then break; fi; cat Q.err > Q.java; done
Potrebbe non essere il più breve, potrebbe non essere nemmeno il più lungo, più una prova di concetto. Funziona perché l'output degli errori mostra al massimo 100 errori.
