Guys I think I understand and agree with the changes you've made... as you tighten up the implementation of DS, old code that used to 'get away with it' needs to break...
But you can't blame me for trying to reverse this change... I have a couple of sad faced developers back here that now need to change and retest their code ;-) I'll await any final fix and in the mean time change our use of BasicAttributes().

We cannot do that. The old behavior was just plain wrong.

However, I now have code that used to work with DS 1.0.0 that no longer works with DS 1.0.2, furthermore I have code that will work if used with a remote context (i.e. via LDAP communications) and won't if I run with an embedded directory context. It's the inconsistent behaviour of the same interface between versions and remote/local contexts that I have found confusing. Is there any way we can have the old behaviour back where it didn't see to matter what type of BasicAttributes() we used? :o) Kind Regards Simon Temple 01 June 2007 15:58 To: "Apache Directory Developers List" <[email protected]>, [EMAIL PROTECTED] cc: From: "Alex Karasulu" <[EMAIL PROTECTED]> Subject: Re: NPE Defect in Latest Directory - 1.0.2 +1 on all of Emmanuel's points. Let me add one additional option. We could write some protective code to detect when the BasicAttributes is created without the boolean argument for ignoring case. We should have some kind of RuntimeException for it. Could be a ConfigurationException maybe? Don't know exactly but basically we need: BasicAttributes attrs = ... if ( ! attrs.isCaseIgnored() ) { throw new "something that tells the user to correct this miss configuration of BasicAttributes"; } WDYT?

Now, regarding Attributes(), you should *always* pass true as an argument. This is a major drawback of JNDI as a generic API for directory, because it does not take into account the underlying directory it has to deal with. There is nothing we can do about it, except fixing NPEs, when it comes to use ADS embedded (meaning : without the network layer which automatically substitutes BasicAttributes to a more ldap compliant BasicAttributesImpl...)
