Here's an example that throws the TokenMgrError.
import org.apache.lucene.queryParser.*;
import org.apache.lucene.search.*;
import org.apache.lucene.index.*;
import org.apache.lucene.analysis.*;
import org.apache.lucene.analysis.standard.*;
import org.apache.lucene.document.*;
public class ParseTest {
public static void main(String args[]) throws Exception {
Analyzer analyzer = new StandardAnalyzer();
IndexReader reader = IndexReader.open("index");
Searcher searcher = new IndexSearcher(reader);
String qStr = "[]";
Query query = QueryParser.parse(qStr, "text", analyzer);
}
}

Actually, this is not quite correct.
It throws a ParseException if it encounters a valid sequence of tokens
but which do not match the parsing rules. For example, I'll bet
foo AND AND bar
would throw a ParseException, even though this is a sequence of valid
tokens.
It throws a TokenMgrError when it cannot even assemble a sequence of
characters into a token. This shouldn't happen; post the offending
query and I'll see if it can be fixed.
