Spring Data JPA - PersistenceException thrown

In a Spring-managed application that has 2 EntityManagerFactories (one Hibernate and one ObjectDB), I see the 2 EMFs created successfully on startup, but then subsequently when the application is initializing Spring JPA repositories with Hibernate EntityManagers, the application throws the following stacktrace.

First query takes 4+ minutes to complete

Hi, we are evaluating ObjectDB 2.5.1_04 in embedded mode hoping to replace SQLite in our application. We observed that in our case it takes on average more than 4 minutes to complete the first SELECT query that we run on the DB which contains about 320,000 records of a single type of object. SQLite in comparison responds within few seconds on average with the same number of records. We hope to receive your recommendation on how to improve this result with this post.   Test System #1 2013-08-05 05:44 Hi, we are evaluating ObjectDB 2.5.1_04 in embedded mode hoping to replace SQLite in our application. ...

Doctor - high memory usage

Hi, Is it possible to reduce Doctor memory usage? Right now for recovering 67MB database, I need to set heap space to at least 450MB. Even then whole process takes ages.
