      Description

      As datasource is a mysql via jdbc configured in the DIH. There are some sql statements in entities, that delivers NULL values in some fields.
      When this entities do have processor="CachedSqlEntityProcessor", a NullPointerException will be thrown. I Tried it on different machines, with different copies of the index.

      e.g.:
      <entity processor="CachedSqlEntityProcessor"
      name="locator_ids"
      query="
      SELECT l1.id AS l1id, l2.id AS l2id, l3.id AS l3id, l4.id AS l4id, l5.id AS l5id, l6.id AS l6id, l7.id AS l7id FROM locators l1
      LEFT JOIN locators l2 ON l1.parent_id = l2.id

      .... and so on delivers a result like:

      -------------------------------

      l1id l2id l3id l4id l5id l6id l7id

      -------------------------------

      21843 855 223 66 12 1 NULL

      -------------------------------

      The SortedMapBackedCache throws the NullPointer.

      at org.apache.solr.handler.dataimport.DocBuilder.buildDocument(DocBuilder.java:683)

      I had to give an onError="continue" to the entity, in order to get the proper stacktrace. Leaving out the onError property (default=Abort) suppresses the stacktrace in EntityProcessorWrapper.java line 332

      The DIH version 3.5.0 is not affected, works fine for me
