Oracle 'raw' column data type is supported?

[Lixo Aqui <li...@netcabo.pt>]

I'm using Solr 1.4.1 and I have a table where the join colum is Oracle RAW.Consider the next example and that id is of ORACLE RAW type. Does Solr support this?
<dataConfig>  <dataSource type="JdbcDataSource"               driver="com.mysql.jdbc.Driver"              url="jdbc:mysql://localhost/dbname"               user="user-name"               password="password"/>  <document>    <entity name="outer"             query="select id,name,desc from mytable">       <field column="id" name="solr_id"/>       <field column="name" name="solr_name"/>       <field column="desc" name="solr_desc"/>       <entity name="inner"               query="select details from another_table where id ='${outer.id}'">              <field column="details" name="solr_details"/>        </entity>    </entity>  </document></dataConfig>
I tried it and the inner query doesn't work because the value passed is something like '[B@d738a2'. Tipical problem of loading the data with a Byte Array and then doing a .toString() on it.My doubt is if this is a bug on Solr, if it's just not supported or do I need to configure something else.

Thanks in advance
