Emmanuel Lecharny commented on DIRSERVER-2231:
----------------------------------------------
You are absolutely right.
The code should looks like :
{code:java}
...
Dn dn = null;
try
{
rwLock.readLock().lock();
if ( entryDnCache != null )
{
Element el = entryDnCache.get( id );
if ( el != null )
{
return ( Dn ) el.getObjectValue();
}
}
...
{code}
