Description

Repro:

org.apache.solr.parser.QueryParser queryParser = ...
queryParser.parse("/* foo */ bar"); // works fine
queryParser.parse("/*"); // fails with SyntaxError, which is correct.
queryParser.parse("/* foo */ bar"); // Fails with SyntaxError. This is the bug
queryParser.parse("bar"); // works fine
queryParser.parse("/* foo */ bar"); // Still failing with SyntaxError

The last parse call will continue to fail for expressions containing comments. Only way to work around that I've found it to create a new instance of QueryParser.
