-------------------------------------
Summary: NPE in LevelDB component when aggregator completionSize =
1
Key: CAMEL-7146
URL: https://issues.apache.org/jira/browse/CAMEL-7146
Project: Camel
Issue Type: Bug
Components: camel-leveldb
Affects Versions: 2.12.2
Reporter: Stefan Burkard
Priority: Trivial
Attachments: Camel-7146-stacktrace.txt
A Camel aggregator with persistence repository of type LevelDB cannot have a
completionSize of 1. If this is configured, every message produces a NPE with
the attached stacktrace.
I have also attached a small example project that shows the Exception. As soon
as the completionSize is > 1, it runs fine.
This is just a minor flaw, since I cannot think about a really useful case with
completionSize 1, but it technically works with other repository types.
As an alternative (if completionSize 1 should not be used), Camel could throw
an error during Context startup when completionSize < 2.
