ItemStateMap warnings during node type changes
----------------------------------------------
Key: JCR-2617
URL: https://issues.apache.org/jira/browse/JCR-2617
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-core, nodetype
Affects Versions: 2.1.0
Reporter: Jukka Zitting
Assignee: Jukka Zitting
Priority: Minor
As reported already in JCR-1105, the ItemStateMap logs warnings when a cached
item state is being overwritten. This shouldn't normally happen, but it turns
out that virtual item state providers do this when the root of the virtual tree
is modified. Probably the most common such situation is when node types are
being modified. This case is luckily not troublesome for the virtual tree
functionality, but the logged warnings are annoying.
Here's a relevant part of a stack trace where this problem occurs:
