Milosz Tylenda commented on OPENJPA-1248:
-----------------------------------------
The problem with SQL Server is that an InputStream obtained from
ResultSet.getBinaryStream can't be used after its result set is closed. OpenJPA
closes the ResultSet before user has a chance to read from the InputStream.
I am investigating these ideas:
1. Using ResultSet.getBlob.getBinaryStream instead of ResultSet.getBinaryStream.
2. Proxying the ResultSet to defer its closing.
> LOB streaming does not work as expected
