Marcel Reutegger closed JCR-454:
--------------------------------
Fix Version: 1.1
Resolution: Fixed
There was a bug in the CachingHierarchyManager which removed a cache entry
instead of evicting it during a LRU remove cycle.
Fixed in revision: 412712
> Query with document order fails when result set size > caching hierarchy
> manager size

> Key: JCR-454
> URL: http://issues.apache.org/jira/browse/JCR-454
> Project: Jackrabbit
> Type: Bug
> Components: core
> Versions: 1.0, 1.0.1, 0.9
> Environment: r412344
> Reporter: Marcel Reutegger
> Assignee: Marcel Reutegger
> Priority: Minor
> Fix For: 1.1
> Attachments: CachingHmgrTest.java
>
> When a query returns a lot of nodes in the query result and document order is
> enabled (which is the default) then the query will fail with error messages
> in the log:
> *ERROR* [main] DocOrderNodeIteratorImpl: Internal error: unable to determine
> document order of nodes: (DocOrderNodeIteratorImpl.java, line 241)
> *ERROR* [main] DocOrderNodeIteratorImpl: Node1:
> /stuff/node[2]/node[13]/node9 (DocOrderNodeIteratorImpl.java, line 242)
> *ERROR* [main] DocOrderNodeIteratorImpl: Node2:
> /stuff/node[2]/node[13]/node5 (DocOrderNodeIteratorImpl.java, line 243)
> The critical size seems to be equivalent to the cache size of the caching
> hierarchy manager. Attached are two test cases. The first one simply creates
> test nodes and the second one executes a query for those nodes. Using the
> cache size of 10'000 in the CachingHierarchyManager#DEFAULT_UPPER_LIMIT
> everything works fine, but when this value is set to 1000 (you need to
> re-compile the class CachingHierarchyManager) the test fails with the
> mentioned errors.
