Querying error - java.lang.ClassCastException: com.objectdb.o.STV

I'm getting the ClassCastException below when querying objects. As yet I haven't been able to track down the exact circumstance in which it occurs - saving and querying objects works fine on attempts to recreate - but presumably at some point an object gets saved which objectdb doesn't like. Any pointers as to what is wrong or approaches to investigate further would be much appreciated. Bug Version: 2.0.5 Priority: Critical Status: Fixed Replies: 6 Type:  Bug ...

Slow searching with two indexes

I'm running queries on a large database (tens of millions of objects), and I'm running into a performance problem using two indexes.  An entity I'm querying has two indexed fields - one is the primary key (id) and so is different for each object, and the other is an object reference that only has a few tens of different values.   When I query by just the primary key, it's (of course) extremely fast, but when I also query using the other key, queries can take minutes.... further, and I have the query logs from using the Database Explorer: SELECT FROM NmeaBatch WHERE receiver == :r ...
