org.apache.mina.filter.codec.ProtocolDecoderException: java.lang.OutOfMemoryError: ;
------------------------------------------------------------------------------------

                 Key: DIRAPI-54
                 URL: https://issues.apache.org/jira/browse/DIRAPI-54
             Project: Directory Client API
          Issue Type: Bug
    Affects Versions: 1.0.0-M8
         Environment: jdk1.6, windows 7, Apache Directory Studio Version: 1.5.3.v20100330,
apache ldap API, apache-ldap-api-1.0.0-M8-bin
            Reporter: Aswartha N Rupa
            Priority: Blocker
             Fix For: 1.0.0-M8


A simple program that performs a search on the sample ldif shipped with apache DS>

public class List {

	public static void main(String[] args) throws Exception{
		LdapConnection connection = new LdapNetworkConnection( "localhost", 10389 , false);
		System.out.println("got connection");
		
        connection.bind( "uid=admin,ou=system", "secret" );
        SearchRequest searchRequest = new SearchRequestImpl();
        searchRequest.setBase(new Dn("ou=Users,dc=example,dc=com"));
        searchRequest.setFilter("(&(sn=*)(mail=mplanck*))");
        searchRequest.setScope(SearchScope.ONELEVEL);
        String [] attributes = { "cn", "mail", "telephonenumber" };
        searchRequest.addAttributes(attributes);
      
        SearchCursor cursor = connection.search(searchRequest);
        
        if (cursor.next()) {
        	Response response = cursor.get();
        	System.out.println( ((SearchResultEntry)response).getEntry() );
        	System.out.println( "Trying to close the cursor" );
            cursor.close();
        	
        }
        //SearchResultDone done = cursor.getSearchResultDone();
        System.out.println( "Trying to close the connection" );
		connection.close();
		System.out.println( "Trying to close the cursor done" );
	}
}

Its prints the first record and waits for more than 10-15 minutes (after the connection.close()
is invoke on main thread) giving out an outofmemory error on protocol decoder. I see two threads
[NioProcessor] and [NioSocketConnector]  in Running state even after main thread executed
its last statement.

With output: 
log4j:WARN No appenders could be found for logger (org.apache.directory.ldap.client.api.LdapConnectionConfig).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
