JPA frustration of the day:

Why can’t I override an @ElementCollection in a subclass?

I just want to change the table name without redefining the entire map in the concrete class! But no, JPA doesn’t support @AttributeOverride for @ElementCollection, so I’m stuck copy-pasting.

Hibernate, please, let me override collection mappings like normal fields!

@Crell 10 years ago, I felt the same, until I realised that I just lacked XP on these very powerful technologies. Sadly, most projects are devastated by developers that don't use them correctly, because they just "hate" it, so just don't learn it.
What I hate today: thousands of lines of SQL code, some dynamically built with string fragments (even to an embryon of a badly designed ORM..) that is so difficult to maintain as it mostly fails at runtime

If Gavin King was part of the Fediverse I would reply to this post twitter.com/1ovthafew/status/1 with the observation, that in Java references have directions. So we naturally build a forest of trees in memory. Probably we don't realize, that merging all those trees into one data model will not result in one bigger tree but in a graph with uni- and bidirectional edges.

X (formerly Twitter)Gavin King ⍼⍼⍼ (@1ovthafew) on XSpeculation: folks with CS degrees love trees. Trees are yall's favorite thing. And a lot of suffering people experience with ORM comes from trying to find trees where they don't exist. Most data models simply don't have any intrinsic treelike structure.
