After reading this forum post :

I created a Singleton For Standard Analyzer too. But the problem still
persists.
I have 2 singletons now. 1 for Standard Analyzer and other for
IndexSearcher.
The code is as follows :
package watchlistsearch.core;
import java.io.IOException;
import org.apache.lucene.search.IndexSearcher;
import org.apache.lucene.store.Directory;
import org.apache.lucene.store.RAMDirectory;
import watchlistsearch.utils.Constants;
public class IndexSearcherFactory {
private static IndexSearcherFactory instance = null;
private IndexSearcher indexSearcher;
private IndexSearcherFactory() {
}
public static IndexSearcherFactory getInstance() {
if (IndexSearcherFactory.instance == null) {
IndexSearcherFactory.instance = new
IndexSearcherFactory();
}
return IndexSearcherFactory.instance;
}
public IndexSearcher getIndexSearcher() throws IOException {
if (this.indexSearcher == null) {
Directory directory = new
RAMDirectory(Constants.INDEX_DIRECTORY);
indexSearcher = new IndexSearcher(directory);
}
return this.indexSearcher;
}
}
package watchlistsearch.core;
import java.io.IOException;
import org.apache.log4j.Logger;
import org.apache.lucene.analysis.standard.StandardAnalyzer;
---------------------------------------------------------------
public class AnalyzerFactory {
private static AnalyzerFactory instance = null;
private StandardAnalyzer standardAnalyzer;
Logger logger = Logger.getLogger(AnalyzerFactory.class);
private AnalyzerFactory() {
}
public static AnalyzerFactory getInstance() {
if (AnalyzerFactory.instance == null) {
AnalyzerFactory.instance = new AnalyzerFactory();
}
return AnalyzerFactory.instance;
}
public StandardAnalyzer getStandardAnalyzer() throws IOException {
if (this.standardAnalyzer == null) {
this.standardAnalyzer = new StandardAnalyzer();
logger.debug("StandardAnalyzer Initialized..");
}
return this.standardAnalyzer;
}
}
