Unfortunately, the first test was way too complicated, because I 
extracted it from my application code instead of trying to just cause 
the hang. The attached causes the same hang with a lot 
less code.
I'll look into 1.0-SNAPSHOT asap.

> When running the attached test, the directory server hangs after executing a slew of
operations when searching for objects.
> First of all, some background on the test case:
> The attached test case (in the form of an exported eclipse project) is, unfortunately,
based on quite a few classes. They are part of a project I am currently working on: an object
to ldap mapper with a similar approach as castor for XML or hibernate for RDBMS, albeit a
lot more modest in complexity (I'll, hopefully, one day be able to open-source it - for now
it is still much to immature). I have supplied all that stuff mainly for your reference.
> To run the test case, please make sure that the constant "URL" in LDAPDirectoryTest points
to a valid directory. The URL the context points to must exist. It will, however, subsequently
create lots of nodes below it.
> The hang seems to be related to some kind of deadlock, since it doesn't occur once the
whole test is run via a single context only. To achieve this, set the constant "ONE_CONTEXT"
to true (each LDAPDirectory uses its own set of contexts).
> If you have any problems running the test, please don't hesitate to contact me.
