Two comments: you'll need to post a minimal example; your example 
works fine for me, so it's not xetex per se. As you work the file 
down to the minimum that fails, you will probably find that some 
other package is causing the problem.

\documentclass{article}
\usepackage{xltxtra}
\usepackage{pst-jtree}
\begin{document}
\jtree
\! = {poem}
     <left>{line} ^<vert>{line} ^<right>{line}.
\endjtree
\end{document}


Second, you'll probably get more help posting your minimal example 
(not just a fragment) to the ling-tex mailing list instead of here, 
since the jtree packages probably unknown outside of linguistics.
