[jira] [Created] (SLING-7154) SlingServletResolver should use a LRU map to cache resolved servlets

Jörg Hoh created SLING-7154:
-------------------------------

             Summary: SlingServletResolver should use a LRU map to cache resolved servlets
                 Key: SLING-7154
                 URL: https://issues.apache.org/jira/browse/SLING-7154
             Project: Sling
          Issue Type: Improvement
          Components: Servlets
    Affects Versions: Servlets Resolver 2.4.14
            Reporter: Jörg Hoh


The ServletResolver currently uses a simple Map to hold the resolved servlets; when reached the cache is full, it does not purge old/unused entries, but just warns (once!), and then silently bypasses the cache and resolves the script again.

It should rather use a LRU cache to hold recently resolved servlets, which makes it possible to adapt to the current workload instead of being stuck to the workload during the filling of the cache.
