Marcel Reutegger created OAK-778:
------------------------------------
Summary: Recursive wrapping of ModifiedNodeState
Key: OAK-778
URL: https://issues.apache.org/jira/browse/OAK-778
Project: Jackrabbit Oak
Issue Type: Bug
Components: core
Reporter: Marcel Reutegger
Priority: Minor
There seem to be cases where a SecureNodeState wraps a ModifiedNodeState, which
in turn wraps a whole chain of other ModifiedNodeStates. A stack trace from one
of the oak-core tests looks like this:
