WRT the "new Compiler" problem, xalan developers removed
static methods from the FunctionTable class.

Yep, all true.
Instantiating a FuntionTable is simple - org.apache.xpath.XPath does it 
like this:

        private void initFunctionTable(){
                    m_funcTable = new FunctionTable();
        }

Thanks for the tip.

However, fixing this issue means that xindice must upgrade to the
latest release of xalan (and that may cause problems for people
who must use older release for some other reasons).
Could use reflection to detect which constructor is available (old or new)
and be compatible with either old or new xalan library.
Yep. It'd be nice to have migration path though. The change has not been 
released yet so we probably still have a chance.

Hi All,
It seems that Xalan XPath API has been changed [1] some time ago, this 
change was not backward compatible, and old method was not deprecated 
but removed completely. This can be seen in Gump messages [2] (snippet 
below).

Would it be possible to re-instate old API, you can make it 
deprecated, but please provide smooth migration path for the 
downstream projects?

Xindice depends on old API, and without deprecation messages it's not 
possible to see what is the proper migration path.

Thanks,
Vadim
