Emmanuel Lecharny commented on DIRSERVER-1121:
----------------------------------------------

Can someone evaluate this issue, and see if it is possible to fix it in 1.5.2 ?

Thanks !

> org.apache.directory.server.core.authz.GroupCache.initialize() creates a filter and subsequently
performs a search using the same filter object on different suffixes. When passed to a JDBMPartition,
org.apache.directory.server.core.partition.impl.btree.DefaultOptimizer.annotate() adds annotations
to nodes in the filter. The same filter is then passed with all the annotations to subsequent
searches on other parititions. When passing to an alternate custom partition implementation,
these annotations get in the way because the printToBuffer() functionality of each filter
node includes annotation information in the serialized form of the filter making it unusable.
> Providing a way to recursively remove annotations would provide a workable bandaid for
this specific problem, though it is probably a bad idea to reuse a filter that has been previously
annotated, so either the partition should make a copy before annotating or GroupCache (and
any other code that uses the same filter reuse paradigm) shouldn't be reusing the filter.
