Richard S. Hall commented on FELIX-338:
---------------------------------------

The LDAP package is self-contained. I don't think it is a good idea to move 
LDAP code outside the LDAP package, nor is it a good idea to duplicate that 
code elsewhere, since code duplication is a maintenance headache. Perhaps it 
would be possible to modify Evaluator.evaluate() method to accept both the 
program and the mapper so that it can be re-entrant?

> Executing a Filter implemented by the Felix Framework FilterImpl class is not 
> thread safe, as the Filter.Implmatch() methods are not synchronized but use a 
> Mapper and Evaluator instance fields which are modified while matching the 
> filter.
> Two options seem to exist:
>    1. Make the match() methods synchronized
>    2. Create Mapper and Evaluator instances on each match() call
> My assumption is that the second method tends to be better because of the 
> synchronization needed with the first approach.
