Solr error creating core: fieldType [x] not found in the schema

Question

I am trying to get a Solr core running with my own schema.xml, but Solr (version 5.2.1) keeps complaining about missing fieldType elements that aren't even in my fields definitions.

org.apache.solr.common.SolrException: fieldType 'booleans' not found in the schema

Whenever I add a 'missing' fieldtype another error pops up complaining about another fieldType missing, like longs, etc., until I've added them all and the schema is accepted without error.

Now how come I must provide these fieldtype elements when there is no use for them?

In config.xml I have:

<schemaFactory class="ClassicIndexSchemaFactory"/>

Here's my schema.xml:

<schema name="collections" version="1.5">

<fields>
    <field name="id_object" type="string" indexed="true" stored="true" />
    <field name="id_organization" type="string" indexed="true" stored="true"  />
    <field name="title" type="string" indexed="true" stored="true"  />
    <field name="artist" type="string" indexed="true" stored="true"  />
    <field name="searchname" type="string" indexed="true" stored="true"  />
    <field name="technique_group" type="string" indexed="true" stored="true"  />
    <field name="technique" type="string" indexed="true" stored="true"  />
    <field name="color_type" type="string" indexed="true" stored="true"  />
    <field name="color" type="string" indexed="true" stored="true"  />
    <field name="subject" type="string" indexed="true" stored="true"  />

    <field name="price_rental" type="tfloat" indexed="true" stored="true"  />
    <field name="price_rental_with_savings" type="tfloat" indexed="true" stored="true"  />
    <field name="savings_portion" type="tfloat" indexed="true" stored="true"  />
    <field name="year" type="tint" indexed="true" stored="true"  />
    <field name="is_for_rent" type="boolean" indexed="true" stored="true"  />
    <field name="is_for_sale" type="boolean" indexed="true" stored="true"  />
    <field name="status" type="string" indexed="true" stored="true"  />
    <field name="shipment" type="tfloat" indexed="true" stored="true"  />
    <field name="timestamp" type="tdate" indexed="true" stored="true" default="NOW" />

    <!-- catch all field, must be multiValued if any of its source fields is -->
    <field name="quick_search" type="text" indexed="true" stored="false" />

    <!-- mandatory -->
    <field name="_version_" type="tlong" indexed="true" stored="true" />

</fields>

<uniqueKey>id_object</uniqueKey>

<copyField source="id_object" dest="quick_search" />
<copyField source="title" dest="quick_search" />
<copyField source="artist" dest="quick_search" />
<copyField source="searchname" dest="quick_search" />
<copyField source="technique_group" dest="quick_search" />
<copyField source="technique" dest="quick_search" />
<copyField source="color_type" dest="quick_search" />
<copyField source="color" dest="quick_search" />
<copyField source="subject" dest="quick_search" />

<types>
    <fieldtype name="string" class="solr.StrField" />
    <fieldtype name="boolean" class="solr.BoolField" />
    <fieldtype name="tint" class="solr.TrieIntField" />
    <fieldtype name="tlong" class="solr.TrieLongField" />
    <fieldtype name="tfloat" class="solr.TrieFloatField" />
    <fieldtype name="tdate" class="solr.TrieDateField" />
    <fieldtype name="text" class="solr.TextField"/>
</types>

</schema>

There is not a single multiValued field in there. Nonetheless I tried explicitly setting multiValued='false' for each field individually, but to no avail. Even when I strip the entire schema down to just a handful of String fields it still generates that error.

I'm pretty confident my schema.xml is OK but perhaps some setting somewhere should tell Solr to take it easy.

Not sure whether it is the preferred way to go, but commenting out the solr.AddSchemaFieldsUpdateProcessorFactory section in config.xml seems to solve the issue.

<!--
<processor class="solr.AddSchemaFieldsUpdateProcessorFactory">
  <str name="defaultFieldType">strings</str>
  <lst name="typeMapping">
    <str name="valueClass">java.lang.Boolean</str>
    <str name="fieldType">booleans</str>
  </lst>
  <lst name="typeMapping">
    <str name="valueClass">java.util.Date</str>
    <str name="fieldType">tdates</str>
  </lst>
  <lst name="typeMapping">
    <str name="valueClass">java.lang.Long</str>
    <str name="valueClass">java.lang.Integer</str>
    <str name="fieldType">tlongs</str>
  </lst>
  <lst name="typeMapping">
    <str name="valueClass">java.lang.Number</str>
    <str name="fieldType">tdoubles</str>
  </lst>
</processor>
