Simon Endele created SOLR-5249:
----------------------------------
Summary: ClassNotFoundException due to white-spaces in
solrconfig.xml
Key: SOLR-5249
URL: https://issues.apache.org/jira/browse/SOLR-5249
Project: Solr
Issue Type: Bug
Components: SearchComponents - other
Reporter: Simon Endele
Priority: Minor
Due to auto-formatting by an text editor/IDE there may be line-breaks after
class names in the solrconfig.xml, for example:
{code:xml}<searchComponent class="solr.SpellCheckComponent" name="suggest">
<lst name="spellchecker">
<str name="name">suggest</str>
<str
name="classname">org.apache.solr.spelling.suggest.Suggester</str>
<str
name="lookupImpl">org.apache.solr.spelling.suggest.fst.WFSTLookupFactory
</str>
[...]
</lst>
</searchComponent>{code}
This will raise an exception in SolrResourceLoader as the white-spaces are not
stripped from the class name:
{code}Caused by: org.apache.solr.common.SolrException: Error loading class
