Hello,

one special of the set of entites, the annotation have a 'mapped by' configuration.

we found a 'workaround': we first access this Set of entites, before we do some other stuff.

(Changed Priority from high -> Normal)
 

Please try build 2.7.0_04.

Hello,

unfortunately the issue is not solved with 2.7.0_04.

So we stay with our workaround (from post#2).

You can try version 2.7.1 that hopefully will solve this exception.

The new version fixes a critical bug that in some cases (rare but possible) may cause database corruption, so it is highly recommended to use the new build.
