Hi,
I'm hunting a spurious RuntimeException from ObjectReferenceDescriptor#getForeignKeyFieldDescriptors() with OJB 1.0.1:
public FieldDescriptor[]
getForeignKeyFieldDescriptors(ClassDescriptor mif)
[..]
if (fkfd == null)
{
throw new OJBRuntimeException("Incorrect or not
found field reference name '"
+ fk + "' in descriptor " + this + " for
class-descriptor '"
+ mif.getClassNameOfObject() + "'");
}This Exception occurs only, if the number of objects, that are stored in the database tables exceeds about 25000 or 30000. My test suite contains a lot of tests, that currently only use some dozens of objects - and the tests is always green.
If traced the problem down to RsIterator#getObjectFromResultSet()
// 2. check if Object is in cache. if so return cached version.
result = getCache().lookup(oid);
if (result == null)
{
where the oid and the result from the cache do not match. At http://www.mitglied.lycos.de/zeppesch/snapshot1.png there is a screenshot, which shows this very clearly.
Unfortunately, this happens just from time to time. Might be a race? Or is there a known OJB problem with multi-field primary keys? Or do I have to further investigate my code? Any hints?
