Peter, I repeated the steps you described and I can confirm that with the -classpath argument the compilation fails and without it the compilation succeeds. I also tried running javac on "src/test/*.java" instead of "src/test/Test3.java". In this case, the compilation succeeds with or without -classpath.
I think it looks like some dependency problem. Chavdar On 10/17/06, Chavdar Botev <[EMAIL PROTECTED]> wrote:
