It is not fixed for oracle. It uses & in bitwise and operations, while it should call function bitand.

Tests added to support this is not an issue in rev 4498.
Probably fixed with the new parser.

Stefan, you can probably use specific function which you can register in the dialect. It won't be like

(x & 1)

but be like

band(x,1)

probably works.

I added this into my configuration:
<property name="query.substitutions">bw_or=^, bw_and=&amp;, bw_not=~</property>
It works, but it's not nice. I have many configuration files for tests and development and production. This is hard to maintain. Would be really nice if NHibernate would support it.
