Hi,
a few days ago I switched the Hibernate version from 4.2.7 (JPA2) to 4.3.1
(JPA2.1) on an existing (spring) application.
Everthing seems to work fine but I was wondering why the application slows
down. Then I detected a very big H2 trace file (.trace.db) only containing
'The object is already closed' org.h2.jdbc.JdbcSQLExceptions.
It seems that nearly every Update and Insert statement throws this
exception.
Going back to Hibernate 4.2 and the exceptions are thrown no longer.
This can be seen by using H2 Version 1.3.175 and Version 1.3.174 (in
embedded mode).
Any ideas on this? How can I change the Hibernate, Spring and/or H2
configuration to avoid this?
Best regards
Axel
