James Dyer commented on SOLR-4361:
----------------------------------

Example from user list:

I've just tried to upgrade from 4.0 to 4.1 and I have the following
exception when reindexing my data:

Caused by: java.lang.UnsupportedOperationException

It seems to be related to the use of placeholders in data-config.xml:

<dataConfig>
    <dataSource type="JdbcDataSource"
                name="bceDS"
                driver="${dataimporter.request.solr.bceDS.driver}"
                url="${dataimporter.request.solr.bceDS.url}"
                user="${dataimporter.request.solr.bceDS.user}"
                password="${dataimporter.request.solr.bceDS.password}"
                batchSize="-1"/>

solrconfig.xml:

<requestHandler name="/dataimport"
class="org.apache.solr.handler.dataimport.DataImportHandler">
 <lst name="defaults">
<str name="config">data-config.xml</str>

<!-- dataSource parameters for data-config.xml -->
<str name="solr.bceDS.driver">...</str>
 <str name="solr.bceDS.url">...</str>
<str name="solr.bceDS.user">...</str>
 <str name="solr.bceDS.password">...</str>
</lst>
</requestHandler>

> If the user puts placeholders for request parameters and these contain dots, DIH fails.  Current workaround is to either use no dots or use the 4.0 DIH jar.
