Tracked this down, it was caused by HHH-4848 on Wed Feb 3 06:58:46 2010 +0000
see:

The check used to skip null values with a continue, but was changed to throw an exception. As such HHH-10956 is a regression caused by HHH-4848

Quick sample project to show case the bug with a composite key and a part of it should be generated.

Was test using the latest version of Hibernate 5.4.0.CR2.
Changing the @GeneratedValue from SEQUENCE to IDENDITY still make the same error.

Edited

This bug still exist in version 5.2.17.

I have the same error with HSQLDB when running my tests.
The ID is generated using a SEQUENCE.
