Subject [jira] [Created] (OAK-7694) Oak.OakDefaultComponents.INSTANCE is mutable
Date Wed, 08 Aug 2018 15:56:00 GMT
Marcel Reutegger created OAK-7694:

             Summary: Oak.OakDefaultComponents.INSTANCE is mutable
                 Key: OAK-7694
                 URL: https://issues.apache.org/jira/browse/OAK-7694
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: core
    Affects Versions: 1.8.0
            Reporter: Marcel Reutegger
            Assignee: Marcel Reutegger
             Fix For: 1.10

The {{OakDefaultComponents}} inside the {{Oak}} builder class was introduced with OAK-6826
and provides a set of default components. Those components can be overridden by calling the
various {{Oak.with()}} methods.

There is a problematic {{OakDefaultComponents}} singleton {{INSTANCE}} used by {{Jcr}}. The
singleton is mutable and may leak modifications from one {{Jcr}} instantiation to another
one. More specifically, the {{SecurityProvider}} has a couple of configurations that extend
{{ConfigurationBase}} with multiple setters.
