[jira] [Updated] (DERBY-6923) Passing a ClientClob or ClientBlob
from another connection results in 'null' being written.
[ https://issues.apache.org/jira/browse/DERBY-6923?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gordon Innes updated DERBY-6923:
--------------------------------
Description:
When assigning a Blob or Clob from a ResultSet to a PreparedStatement parameter on a second connection, null is written to the column instead.
Attached the same example using Embedded->Embedded, Embedded->Network, Network->Embedded and Network->Network.
Only the Network->Network example exhibits the fault.
Originally discovered in HA-JDBC's sync code with 2 derby instances on Windows. Example were tested using MacOS. Both were running on Oracle Java 8 VMs.
