I just ran BlobTest on Derby, and it passes :)
btw, i'm using the latest source from master, and default hibernate.properties in
hibernate-entitymanager/src/test/resource (except the db connection info changed to derby
from h2)

Debugging a BLOB issue on H2 (different issue than this) led me to
try Derby, which fails even earlier.
This is the same test as org.hibernate.ejb.test.lob.BlobTest, if someone could run this
on Derby, you should see the exception. I've copied the test 1:1 into my environment
and had the same exception.
The sql.BlobTypeDescriptor.STREAM_BINDING option is used by default for an @Lob
java.sql.Blob property. This option "unwraps" the value by calling
java.BlobTypeDescriptor.unwrap():
return (X) new BinaryStreamImpl( DataHelper.extractBytes( value.getBinaryStream() ) );
This crashes on the call to value.getBinaryStream():
Caused by: java.sql.SQLException: You cannot invoke other java.sql.Clob/java.sql.Blob
methods after calling the free() method or after the Blob/Clob's transaction has been
committed or rolled back.
