ObjectId already set

[Bios-Marcel]

I am receiving the following error when trying to store an obejct that contains a Lazy<[]byte> field:

java.lang.IllegalStateException: ObjectId already set: 1000000000000000008
	at org.eclipse.serializer.reference.Lazy$Default.validateObjectIdToBeSet(Lazy.java:423) ~[base-1.4.0.jar:?]

What could be the cause of this? I am rather clueless.

So, it appears that this was an issue caused by serialising an object that was previously copied via ObjectCopier. The object in question contained the mentioned Lazy field.

Manually "copying" the field by calling the setter (which creates a fresh Lazy-reference) did the job!

Hope this helps anyone
