I think this is due to an integer overflow.
Earlier StoredPage#readPageHeader is called, and nextId is set to -2147481666.
Before this line in StoredPage#readPageHeader,
{code:java}
nextId = lrdi.nextInt();{code}
lrdi.position = 16, and
lrdi.pageData = (in hex) 007500000001000000017f41de880219800007be0000000000...
I can't provide the entire data base, as it is confidential.
This occurred with derby 10.10.1.0, but I can reproduce it with 10.14.1.0
We do a lot of writes/deletes to this table, it's quite possible we've hit 2
billion inserts/deletes.
