次の Hql クエリに問題があります。
FROM PhysikalischesObjekt physikalischesObjekt LEFT OUTER JOIN FETCH physikalischesobjekt.AktuelleInstallation installation
ご覧のとおり、エンティティのように名前を付けたエイリアスを使用しています（最初の位置に小文字を付けただけです）。
Nhibernate に対してこのクエリを実行すると、InvalidPathException が発生します。
NHibernate.Hql.Ast.ANTLR.InvalidPathException : Invalid path: 'physikalischesobjekt.AktuelleInstallation' [FROM PhysikalischesObjekt physikalischesObjekt LEFT OUTER JOIN FETCH physikalischesobjekt.AktuelleInstallation installation ]

Hql でこのようなエイリアスを使用する際に問題はありますか? エンティティ名と同じエイリアス名の使用を禁止する構文はありますか? Nhibernate は、明らかに機能しないエイリアス名の永続化を見つけようとしているようです。
