Entry Processor Rollback Causes Distributed Service Failure In Backup Node Due to a NullPointerException (Doc ID 1380741.1)

Last updated on SEPTEMBER 11, 2018

Applies to:

Oracle Coherence - Version 3.7.1 and later
Information in this document applies to any platform.
***Checked for relevance on 21-Nov-2013***

Symptoms

To rollback changes from the work done by an EntryProcessor, an exception can be thrown from the EntryProcessor's process() method, as documented in the InvocableMap.EntryProcessor API documentation.

However, if you do this in 3.7.1, then you may see a NullPointerException occuring in the cache service that is responsible for the backup partition for the data being modified.
