[ http://issues.apache.org/jira/browse/DIRSERVER-578?page=comments#action_12366420 ]
Emmanuel Lecharny commented on DIRSERVER-578: --------------------------------------------- I think that this infinite loop is due to the use of '*' instead of '+' in the following antlr rule : SIMPLE_STRING : ( ~( ',' | '=' | '+' | '<' | '>' | '#' | ';' | '\\' | '"' ) )* <-- should be + in the shared/ldap/src/main/antlr/valuelexer.g file. I still have to test it, but it's a little bit late right now, so feel free to change it and rebuild the project. some explanation : with '*', an empty SIMPLE_STRING is valid. So if we have, say, an '=', which is not allowed by any other rule in the production : value ::= ( SIMPLE_STRING | HEX_STRING | QUOTED_STRING | ESCAPED_CHAR )+ we have an infinite loop. > LDAP Name Parser Trapped in Infinite Loop > ----------------------------------------- > > Key: DIRSERVER-578 > URL: http://issues.apache.org/jira/browse/DIRSERVER-578 > Project: Directory ApacheDS > Type: Bug > Components: ldap > Versions: pre-1.0 > Environment: Fedora Core 4 > Reporter: Ole Ersoy > Priority: Minor > > Hi Stefan, > Here's some JNDI JUnit Testing code that runs fine on > 0.9: > package com.pyramidetechnologies.webapp.mdc; > import java.util.Hashtable; > import javax.naming.Context; > import javax.naming.NamingException; > import javax.naming.directory.DirContext; > import javax.naming.directory.InitialDirContext; > import junit.framework.TestCase; > public class LDAPTesting extends TestCase { > public DirContext authenticate() { > try { > Hashtable<String, String> env = new > Hashtable<String, String>(); > // Set up the environment for creating the initial > context > env.put(Context.INITIAL_CONTEXT_FACTORY, > "com.sun.jndi.ldap.LdapCtxFactory"); > env.put(Context.PROVIDER_URL, > "ldap://localhost:389/ou=users,ou=system";); > // Authenticate as S.
