I am trying to use solrj client with solr version 6.2.0 and it seems it is sending false values always even if the actual value is true
I tried to get value using solr web query there the values are right but its just solrj client which is getting wrong values.
Try using solr version 6.2.1 as it seems to be bug with version 6.2.0
They have reported it on link https://issues.apache.org/jira/browse/SOLR-9490
hope it helps!
