Hibernate version: 2.1

I think I have identified a bug in the class BasicPropertyAccessor used by hibernate. I have a bean in which I have properties which are called names like xUnit and zIndex. Notice that the first part of the names are a single letter (x and z respectively). Hibernate is unable to find my corresponding getter methods getXUnit and getZIndex and throws the exception shown below.

I noticed that this only happened for methods which had names in which the first part consisted of only a single char, so out of curriosity I renamed my methods to getXxUnit and getZzIndex and to my surprise it now works. I checked this quite thoroughly for different properties, and it fails consistently - as soon as I use only a single letter as a part of the name, hibernate cannot find the getter.

Does anyone know if this is a known bug or if there is any better workaround?

No, you haven't found a bug, its an FAQ.

Could you please elaborate? Is there a special reason why you get this error when using names like zIndex? Should not zIndex be an allowed property name since zzIndex is an allowed name?

Thank you

Great, I found a work arround on this page:
http://www.hibernate.org/116.html#A33

Still, might I ask why hibernate does not support naming a property zIndex? Since this has been turned into a FAQ I am obviously not the first person to encounter this problem - would it not be a great help, if hibernate was changed to support this? And would it not be trivial to fix this?

It has been a while since I read the JavaBeans spec, but I do not recall any obvious reasons why you should not be allowed to call a bean property zIndex, and, to no surprise, doing so is accepted by the java compiler...
