-----------------------------------------
Summary: Map to Iterable converter regression
Key: CAMEL-13741
URL: https://issues.apache.org/jira/browse/CAMEL-13741
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.20.0
Reporter: Antoine DESSAIGNE
When converting a {{Map}} to an {{Iterable}} the results is no longer the same
since CAMEL-11379.
Given the following context
{code}
<?xml version="1.0" encoding="UTF-8"?>
<routes xmlns="http://camel.apache.org/schema/spring";>
<route>
<from uri="timer:single?repeatCount=1"/>
<setBody>
<groovy>[A: 'aa', B: 'bb', C: 'cc', D: 'dd']</groovy>
</setBody>
<convertBodyTo type="java.lang.Iterable"/>
<split>
<simple>${body}</simple>
<log message="${body}"/>
</split>
</route>
</routes>
{code}
It produces 4 log messages in camel 2.18.3 using the converter
{{CollectionConverter.toSet(java.util.Map<K,V>)}}. Using camel 2.24.1 it
produces only one message containing the whole list. This is due to
{{ObjectConverterOptimised}} calling
{{ObjectHelper.createIterable(java.lang.Object)}} which has a fallback to
{{Collections.singletonList(value)}} thus producing a single entry with the
whole
