Chetan Mehrotra created OAK-4431:
------------------------------------
Summary: Index path property should be considered optional for
copy on read logic
Key: OAK-4431
URL: https://issues.apache.org/jira/browse/OAK-4431
Project: Jackrabbit Oak
Issue Type: Bug
Components: lucene
Reporter: Chetan Mehrotra
Assignee: Chetan Mehrotra
Fix For: 1.6
As part of changes done for OAK-4347 logic assumes that indexPath is always non
null. This works fine for fresh setup where the indexPath would have been set
by the initial indexing. However for upgraded setup this assumption would break
as it might happen that index does not get updated with new approach and before
that a read is performed.
Currently with updated code on upgraded setup following exception is seen
{noformat}
Caused by: javax.security.auth.login.LoginException:
java.lang.NullPointerException: Index path property [:indexPath] not found

For this specific flow the indexPath can be passed in and not looked up from
IndexDefinition
