Hi all,
I'm using Solr 4.9.0 and have setup a spellcheck component for returning
suggestions. The configuration inside my solr.SpellCheckComponent has as
follows.
<str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
<str
name="lookupImpl">org.apache.solr.spelling.suggest.fst.BlendedInfixLookupFactory</str>
along with a custom value for
<str name="indexPath"></str>
The server is starting properly and data gets indexed but once i hit the
'Reload' button from 'Core Admin' I get the following error.

Debugging Solr code I found out that the original exception comes from the
IndexWriter construction inside AnalyzingInfixSuggester.java ( more
specifically org.apache.lucene.store.Lock:89). The exception is "Lock obtain
timed out: NativeFSLock@$indexPath/write.lock" but seems to be hidden by the
RuntimeException thrown by BlendedInfixLookupFactory.
If I use the default "indexPath" I get another error (write lock related
again) in the logs.
