Strange, I don’t remember seeing this error before. It looks like an
Hibernate
bug.
Has been reported as such, and usually rejected, e.g.:
https://hibernate.atlassian.net/browse/HHH-3715
I feel that the problem is that the XWQL-Query is not translated to HQL
properly

doc.object(XWiki.XWikiServerClass).server = :wikiAlias and
doc.name like 'XWikiServer%’"
This is a XWQL query, however, and the HQL that is created from it (I
guess its created from the query, as that is what is shown in the error
message):
select doc.fullName from XWikiDocument as doc , BaseObject as _o1 where (
doc.object ( XWiki.XWikiServerClass ) . server = :wikiAlias
and doc.name like 'XWikiServer%' ) and doc.fullName=_o1.name and
_o1.className='XWiki.XWikiServerClass'
Of course the "( doc.object ( XWiki.XWikiServerClass ) . server" is not
proper HQL, something must have gone amiss when translating the XWQL to HQL.
What puzzles me is why this has something to do with the Oracle driver
(It is no general bug for sure, otherwise it would have blocked any
development ...)
I just checked and I get basically the same error message when I try to
execute the generated HQL "manually" (from a groovy script in a page),
but of course no such error when executing the XWQL (would not have been
able to start the server then).
Is it possible to direct the installation temporarily to e.g. HSQL-DB
(something along
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/InstallationHSQL )
- just for testing if the issue goes away then? (It is sure not useful
for production use that way until switched back to Oracle ...)
If the issue does not go away, then it must be something else ...
