<p style='margin-top:0;margin-bottom:10px;'>I have a cached HQL query that is returning a list with all null values. I'm sorry for not including a test case, but I have already debugged the problem and can describe it in detail below.</p>
<p style='margin-top:0;margin-bottom:10px;'>A bug in hibernate occurs if you try to cache a HQL query that selects an @OneToOne property from a domain object. </p>
<p style='margin-top:0;margin-bottom:10px;'>The problem is in OneToOneType.disassemble() line 175 in verson 4.2.0. The OneToOneType.disassemble() method returns null, but most likely it should do something similar to what is done in ManyToOneType.disassemble(). I actually fixed the bug in my case by stealing code from ManyToOneType from the disassemble and assemble methods, but I'm pretty sure what I did will break other inverse OneToOne caes. When the OneToOneType.disassemble() method is called from StandardQueryCache.put() line 111, because OneToOneType.disassemble() returns null, then a null is incorrectly placed in the cache resulting in a list of null values being returned from the cache when retrieved later. </p>
<p style='margin-top:0;margin-bottom:10px;'>If, however, the property that you are selecting in your JPQL query is a @ManyToOne type then there is no problem at all. My work around for now is to use a @ManyToOne on my property instead, but that won't work in all cases, so I will be waiting for one of your smart engineers to fix this bug. Many thanks!</p>
