object scope search on non-existant DN gives IllegalArgumentException:
"Argument 'an_obj1' is null"
----------------------------------------------------------------------------------------------------
Key: DIRSERVER-759
URL: http://issues.apache.org/jira/browse/DIRSERVER-759
Project: Directory ApacheDS
Issue Type: Bug
Components: core
Affects Versions: 1.1.1
Environment: N/A
Reporter: Norbert Reilly
Fire up a vanilla empty ApacheDS 1.1 instance, and then attempt an object scope
search on a non-existant base DN like "cn=admin,ou=system", with filter
"(objectclass=*)" returning no attributes.
Instead of a NameNotFoundException exception you get the following stack trace:
java.lang.IllegalArgumentException: Argument 'an_obj1' is null

The problem seems to be that in the enumerate method in
ScopeEnumerator.java:67, the following line returns null:
final BigInteger id = db.getEntryId( snode.getBaseDn() );
but nonetheless a IndexRecord is created and returned anyway. I don't know this
code well enough to be certain whether a "LdapNameNotFoundException" should be
thrown at this stage, or whether instead a check for a null IndexRecord id
should be performed later when actually evaluating the filter. If someone more
knowledgeable can offer some advice on this point then I can submit a patch and
testcase.
Note I tested if the same problem occurs in 1.0, and it doesn't.
