Hi, Jehan:
Sakai 2.8.0 uses kernel v1.2.1. Based on the stacktrace below, following
are the relevant code:
BaseUserDirectoryService.java:2455
/**
* @inheritDoc
*/
public int compareTo(Object obj)
{
if (!(obj instanceof User)) throw new ClassCastException();
// if the object are the same, say so
if (obj == this) return 0;
// start the compare by comparing their sort names
int compare = getSortName().compareTo(((User) obj).getSortName());
// if these are the same
if (compare == 0)
{
// sort based on (unique) eid
compare = getEid().compareTo(((User) obj).getEid()); <<<<2455
}
return compare;
}
Looks like some of the site users have null eids. Could you please verify
if this is the case? We need to file a kernel jira for the possible NPE in
the above method.
Thanks,
- Zhen
