H2Dictionary has 'useGetObjectForBlobs' set to true, which should be false
--------------------------------------------------------------------------
Key: OPENJPA-484
URL: https://issues.apache.org/jira/browse/OPENJPA-484
Project: OpenJPA
Issue Type: Bug
Components: jdbc, sql
Affects Versions: 1.0.1, 1.1.0
Environment: H2 Database - v1.0.64, Java SE6
Reporter: Prashant Bhat
>From H2 Database forum
>http://groups.google.com/group/h2-database/browse_thread/thread/fab7dd4424445c9b
H2Dictionary has 'useGetObjectForBlobs' set to true, whereas the default in
DBDictionary is false. So for an entity with a property of type byte[] which is
mapped as blob, loading fails because, the 'getBytes' method uses
'rs.getObject(column);' which fails with the following exception:
Caused by: java.lang.ClassCastException: java.io.ByteArrayInputStream cannot be
cast to [B

I've tried setting 'useGetObjectForBlobs' to false(by just commenting it!), it
is working. So please change this to false.
Thanks,
