Description

As far as I know, this bug is not related to DERBY-428 bug.
I got this bug both on 10.1.3.1 and 10.1.2.1 - an ArrayIndexOutOfBoundsException in DDMReader (in Network Server).

To reproduce the bug:
1. Compile the attached DerbyTest.java
2. Start the Network Server (startNetworkServer.bat under Windows)
3. Run: java DerbyTest

On client side you get:
org.apache.derby.client.am.DisconnectException: The DDM object is not supported. Unsupported DDM object code point: 0x0
