Write a code golf problem in which Java wins
48 characters

Task: Ignore any input. Always produce exactly the following output:

java.lang.ExceptionInInitializerError
Caused by: java.lang.ArithmeticException: / by zero
    at M.&lt;init&gt;(M.java:1)
    at M.&lt;clinit&gt;(M.java:1)


Solution:

enum M{M;System x;{x.setErr(x.out);int y=1/0;}}


Save as M.java, compile with javac M.java and run with java M. It also produces an error message on standard error, but that doesn't violate any of the rules.
