Subject [jira] [Updated] (CAMEL-7146) NPE in Aggregator when completionSize = 1
Date Mon, 03 Feb 2014 15:04:10 GMT

     [ https://issues.apache.org/jira/browse/CAMEL-7146?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Stefan Burkard updated CAMEL-7146:
----------------------------------

    Component/s:     (was: camel-leveldb)
                 camel-core
    Description: 
A Camel aggregator with persistence repository 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 worked with earlier versions of Camel. 

As an alternative (if completionSize 1 should not be used), Camel could throw an error during
Context startup when completionSize < 2.

  was:
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.

        Summary: NPE in Aggregator when completionSize = 1  (was: NPE in LevelDB component
when aggregator completionSize = 1)
