I got the following error when I executed the script:

WARNING: Failed to access http://javadl-esd.sun.com/update/9.0.4/map-m-9.0.4.xml
Exiting without checking the latest Java version numbers or without updating Java (at Step 10).

It looks like there's no such file as http://javadl-esd.sun.com/update/9.0.4/map-m-9.0.4.xml

I tried to translate the URI to https://javadl-esd-secure.oracle.com/ but it seems there's no equivalent path available.
