I compiled your Bug.java with Sun's javac and run it with kaffe,
and found that NoSuchMethodError occurred.

Then I compiled Bug.java with Sun's javac using the option
-target 1.1 and run it with kaffe.  This time the program
ended normally.

Following are the class files generated by Sun's javac
(disassebled by at.dms.dis.Main).
