Description

All search requests fails after few sequiancial of Collection RELOAD requests with using spellcheck component
with AnalyzingInfixSuggester

Observed in Solr 4.6.1

Reproducible steps:
1. Initialized spellcheck component with AnalyzingInfixLookupFactory
2. Consider the collection "test_suggest" (if not create one)
3. Lets have a dictionary file 'dictionary_a.txt' with size in MBs (~20MB). Each line contains a word (max 20char).
4. Now, hit the collection reload (or core reload) few times in sequence. (Make sure that your dictionary files is large enough)

• req (core reload) : GET http://<solrhost>:<port>/solr/admin/cores?action=RELOAD&core=test_suggest
  or
• req (collection reload) : GET http://<solrhost>:<port>/solr/admin/collections?action=RELOAD&name=test_suggest
  5. do the search : GET http://<solrhost>:<port>/solr/test_suggest/suggest_handler?q=dr

Response : All the search requests fails.
Note : Do not turn off buildOnStartup

Sample Configuration:
<searchComponent name="suggest" class="solr.SpellCheckComponent">
<lst name="spellchecker">

<str name="indexPath">./index/analyzingSuggesterIndex_a</str>
<str name="suggestAnalyzerFieldType">text_general</str>
<str name="sourceLocation">./dictionaries/dictionary_a.txt</str>
<str name="buildOnStartup">true</str>
</lst>
</searchComponent>
<requestHandler name="/suggest_handler" class="org.apache.solr.handler.component.SearchHandler">
<lst name="defaults">
<str name="spellcheck">true</str>
<str name="spellcheck.dictionary">suggest</str>
<str name="spellcheck.count">30</str>
<str name="spellcheck.onlyMorePopular">true</str>
</lst>
<arr name="components">
