[jira] [Created] (JCR-3239) Removal of a top level node doesn't update the hierarchy manager's cache.

Removal of a top level node doesn't update the hierarchy manager's cache.
-------------------------------------------------------------------------

                 Key: JCR-3239
                 URL: https://issues.apache.org/jira/browse/JCR-3239
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-core
    Affects Versions: 2.2.11
            Reporter: Philipp Bärfuss
            Priority: Minor


*Problem*

Scenario in which I encounter the problem:
- given a node 'test' under root (/test)
- re-imported the node after a deletion (all in-session operations) 

{code}
session.removeItem("/test")
session.getImportXML("/", stream, ImportUUIDBehavior.IMPORT_UUID_COLLISION_THROW)
{code}

Result: throws an ItemExistsException

If the same operations are executed deeper in the hierarchy (for instance /foo/bar) then the code works perfectly fine.

*Findings*
- session.removeItem informs the hierachy manager (via listener)
--> CachingHierarchyManager.nodeRemoved(NodeState, Name, int, NodeId)
- but the root node (passed as state) is not in the cache and hence the entry of the top level node is not removed
--> CachingHierarchyManager: 458 
- while trying to import the method SessionImporter.startNode(NodeInfo, List<PropInfo>) calls session.getHierarchyManager().getName(id) (line 400)
- the stall information causes a uuid collision (the code expects an exception if the node doesn't exist but in this case it returns the name of the formerly removed node)

Note: session.itemExists() and session.getNode() work as expected (the former returns false, the later throws an ItemNotFound exception)
Note: I know that a different import behavior (replace existing) would solve the issue but I can't be 100% sure that the UUID match so I favor collision throw in my case.
