It appears that it is indeed the default behavior: no matter what you
set, the link always goes to the next slide.

I improved HSLF to support hyperlinks to slides, the fix committed in r1401642

With this fix you don't have to construct the href yourself. There is
a overridden Hyperlink.setAddress(Slide slide) which takes the  target
slide and construct the href internally.

You can follow the example :

https://svn.apache.org/repos/asf/poi/trunk/src/examples/src/org/apache/poi/hslf/examples/CreateHyperlink.java


Twy the latest buuld from trunk. Links to nightly builds are on
