------------------------------------
Summary: PropertyDescriptor must have poredictable iteration order
Key: CAY-1729
URL: https://issues.apache.org/jira/browse/CAY-1729
Project: Cayenne
Issue Type: Bug
Components: Core Library
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
Fix For: 3.1B2, 3.2M1
The fact that PropertyDescriptor.getDeclaredProperties() can return a mix of
attributes and relationships and generally undefined order has already caused
us grief, and will likely be causing some more. Internally properties are
stored in a HashMap, so the order depends on the property names, hashing
algorithm, and sometimes JDK version (if the hashing algorithm changes, like it
did between 1.5 and 1.6)...
A recent manifestation of this problem is described here:
http://markmail.org/message/jwlfkgwz6vloavk4 While current algorithm does not
have bugs by itself, it creates a great deal of uncertainty that makes
reproducing real problems very painful.
Not sure if it makes sense to introduce alpha iteration order of
attributes/relationships (does it buy us any extra consistency?), but it is
quite clear that at least the order of iteration should be (1) all attributes
(2) all relationships. Need to fix it in 3.1 too...
