Thanks for noting those.  I've added those to the IcedTea build system 
as additional locations to check.

I didn't realise we were on b13 (was there any public announcement? 
announce at openjdk.java.net would be a natural place).

I've just downloaded the b13 and tried a build; unfortunately it fails, 
so it looks like b12 is required for now.

The version of jar we are using allows us to omit input files to create 
an empty jar, but it looks like this version doesn't.  As a work-around, 
I've added a dummy input file to the jar command.

These changes (xalan/xerces locations and empty jars) have been checked 
into the IcedTea mercurial repository.
