Jukka Zitting resolved JCR-385.
-------------------------------
Resolution: Fixed
Fixed in revision 544316 by throwing a more descriptive InvalidQueryException
instead of the ClassCastException. Note that such union queries are currently
not supported by Jackrabbit.
Merged to the 1.3 branch in revision 544319.

> The XPathQueryBuilder throws a ClassCastException on line 322 in release 0.9
> when executing syntactically valid union queries. An example query would be
> "//element(*, nt:file) or //element(*, mix:lockable)". It appears that in the
> invocation of the visit method the SimpleNode id indicates a type of
> JJTROOTDESCENDANTS at a certain point but the data is actually an OrQueryNode
> and hence the cast to a PathQueryNode fails.
