Description

Hello,

when we try to read the Root DSE of an Oracle Unified Directory Server (OUD) we get the following stack trace:

{{
org.apache.mina.filter.codec.ProtocolDecoderException: java.lang.NullPointerException (Hexdump: 30 82 01 17 02 01 08 65 07 0A 01 00 04 00 04 00 A0 82 01 07 30 82 01 03 04 17 31 2E 33 2E 36 2E 31 2E 34 2E 31 2E 32 36 30 32 37 2E 31 2E 35 2E 34 01 01 FF 04 81 E4 30 81 E1 04 81 DE 64 63 3D 76 66 64 32 2C 64 63 3D 64 65 3A 30 30 30 30 30 31 37 37 61 64 38 32 32 35 36 32 35 65 39 35 30 30 30 30 30 32 61 39 20 30 30 30 30 30 31 37 37 62 35 37 30 63 63 66 36 30 66 39 62 30 30 30 30 30 35 66 63 3B 6F 3D 74 72 61 6E 73 66 65 72 3A 30 30 30 30 30 31 37 37 62 30 34 61 37 62 37 64 31 34 65 31 30 30 30 30 32 65 65 61 20 30 30 30 30 30 31 37 37 62 35 37 30 64 37 62 38 34 63 36 39 30 30 30 30 30 31 33 65 3B 6F 75 3D 6E 6D 73 2C 64 63 3D 61 72 63 6F 72 2C 64 63 3D 6E 65 74 3A 30 30 30 30 30 31 37 36 36 62 39 34 62 65 62 62 37 33 32 34 30 30 30 30 33 62 64 61 20 30 30 30 30 30 31 37 36 36 61 66 66 39 35 30 34 32 63 34 65 30 30 30 30 34 34 30 62 3B)

}}

Using a debugger, we end up in the code of StoreControlValue Line 80:
{{ControlFactory<?> factory = container.getControlFactory();
factory.decodeValue( control, value.getData() );}}

Here factory is null.

The OID which is evaluated is 1.3.6.1.4.1.26027.1.5.4.

The bug was introduced between Apache Directory Studio M14 and M15.
