[jira] [Created] (DIRSERVER-1627) NullPointerException in
GroupCache.getGroups
NullPointerException in GroupCache.getGroups
--------------------------------------------
Key: DIRSERVER-1627
URL: https://issues.apache.org/jira/browse/DIRSERVER-1627
Project: Directory ApacheDS
Issue Type: Bug
Components: core
Reporter: Mike Adamson
I am getting an intermittent NPE in GroupCache.getGroups at the following location:
for ( Object obj : ehCache.getKeys() )
{
String group = ( String ) obj;
>>> Set<String> members = ( Set<String> ) ehCache.get( group ).getValue();
if ( members == null )
{
continue;
}
This happens after leaving the environment for longer than the default group cache expiry time. I think the default behaviour of ehCache is to remove the value from the cache but not the key until it is accessed.

----------------------------------------------
Very good catch.
The cache should be made eternal. We won't have millions of entries in it.
