This is probably due to the fact that in class org.teiid.translator.odata.ODataTypeManager the following is defined:
{code}
teiidkeyed.put(DataTypeManager.DefaultDataTypes.BYTE, EdmSimpleType.BYTE);
{code}
instead of
{code}
teiidkeyed.put(DataTypeManager.DefaultDataTypes.BYTE, EdmSimpleType.SBYTE);
{code}
The EdmSimpleType.BYTE tries to cast to the build in org.odata4j.core.UnsignedByte type which is not possible for a java.lang.Byte.
