On mysql5, with large file uploade, I see this: | Caused by: org.jboss.util.NestedSQLException: Error; - nested throwable: (java.lang.OutOfMemoryError) | at org.jboss.resource.adapter.jdbc.WrappedConnection.checkException(WrappedConnection.java:557) | at org.jboss.resource.adapter.jdbc.WrappedStatement.checkException(WrappedStatement.java:561) | at org.jboss.resource.adapter.jdbc.WrappedPreparedStatement.executeUpdate(WrappedPreparedStatement.java:255) | at org.hibernate.id.IdentityGenerator$GetGeneratedKeysDelegate.executeAndExtract(IdentityGenerator.java:73) | at org.hibernate.id.insert.AbstractReturningDelegate.performInsert(AbstractReturningDelegate.java:33) | ... 256 more | Caused by: java.lang.OutOfMemoryError | which is normally fixed by increasing the heapsize.
