After replacing 1.2.1 with 1.2.2 and turning on the metadata preload, I
got a nonsensical "column that is not compatible" error. I then tried
removing the preload setting, and it's fine. I set it back, and it
failed again, so it's repeatable.
The relevant part of the stack trace is this (some pieces obscured):
Caused by: <openjpa-1.2.2-r422266:898935 fatal user error>
org.apache.openjpa.persistence.ArgumentException:
"...domain.pricelist.PriceListFolder.childItems<element:class
...domain.pricelist.PriceList>" declares a column that is not compatible
with the expected type "blob". Column details:
Full Name: PRICE_LIST.PRICE_LIST_ID
Type: varchar
Size: 255
Default: null
Not Null: false

Notice that there is no "lob" anywhere. The column it's complaining
about is an ordinary column reference.
