As a workaround (instead of installing Java 7), you can add
wrapper.disable_console_input=FALSE to the Java wrapper config. You can
add this option by editing the file /etc/init.d/djigzo

Change

WRAPPER_OPTS="wrapper.daemonize=TRUE"

To:

WRAPPER_OPTS="wrapper.daemonize=TRUE wrapper.disable_console_input=FALSE"

I'll contact the java wrapper developers. It might be some interaction
bug between changes in Java 6 and java wrapper.

Kind regards,
