Re: [hibernate-dev] Are arrays of non-basic elements supported?
The docs says:
When it comes to arrays, there is quite a difference between Java arrays
and relational database array types (e.g. VARRAY, ARRAY). First, not all
database systems implement the SQL-99 ARRAY type, and, for this reason,
Hibernate doesn’t support native database array types. Second, Java arrays
are relevant for basic types only since storing multiple embeddables or
entities should always be done using the Java Collection API.
I guess the "Second, Java arrays ..." part is indeed a little bit
misleading.
I created the following issue:
https://hibernate.atlassian.net/browse/HHH-11891
Is it a problem if I link the docs to my blog post about how to support
arrays of basic types?

That doc section is wrong. Vlad - can you fix that
We do in fact support arrays of all types including embeddables and
entities. However, we have always recommended to not use arrays for
entities as arrays cannot be lazy loaded (not even using bytecode
enhancement).
