Hi,
I have web application running on Websphere v8.5, that uses a JPA project
configured as utility project. The application suddenly started throwing
ClassCastException when performing select query. I have pasted the exception
stack trace. The weird things is it works sometime and at times I get this
exception. Also, if the DB tables have just one record then everything works
fine, if there are more than 1 record then I see this exception
The entities have a OneToMany and ManyToOne relationships defined.
Caused by: java.lang.ClassCastException: org.apache.openjpa.util.IntId
incompatible with com.jpa.dom.transactionqueue.BlockTransactionQueue
