Eager load Map

I'm having an issue eager loading a nested map. I've attached @ManyToMany(fetch=FetchType.EAGER) attributes to no avail. If the map is viewed in the debugger or force iterated in the code it loads ok. The attached code attempts to replicate the scenario. Its not an exact match but is the best I could come up with without replicating the whole system. The test creates an object, persists it to a db and re-loads it. The EntityManager is closed before accesing any fields. Finally the nested map is accessed and printed to screen. Bug Version: Priority: Normal Status: Fixed Replies: 7 Type:  Bug ...

See JavaDoc Reference Page... . The issue tracking system enables listing all the unsupported JDO features (this ...

Remove an entity which attributes were changed - OptimisticLockException

We use an OSGi environment and we have three OSGi plugins.   In plugin A an entity is loaded and the entity is passed to plugin B. Plugin B changes an attribute on the entity. Plugin C removes the entity from the database. After commit the transaction an exception is caused with optimistic lock exception of the removed entity. If this operations on the entity are executed in only one plugin, it works well. #1 2016-04-14 13:06 We use an OSGi environment and we have three OSGi plugins.   In plugin A an entity is loaded ...
