ClassCast error

[Oleg Cohen <ol...@assurebridge.com>]

Greetings,

I am seeing this exception when my application starts:

java.lang.ClassCastException:
org.apache.jackrabbit.oak.segment.SegmentNodeState cannot be cast to
org.apache.jackrabbit.oak.plugins.document.AbstractDocumentNodeState
at
org.apache.jackrabbit.oak.plugins.document.secondary.SecondaryStoreObserver.contentChanged(SecondaryStoreObserver.java:79)

I wonder if anyone has seen the same and what the problem might be.

Thank you!
Oleg

The exception sounds as if you're trying to use a SegmentStore where a
DocumentStore is expected.
