             Summary: Type converter regression in Camel 3.7.0
                 Key: CAMEL-16000
                 URL: https://issues.apache.org/jira/browse/CAMEL-16000
             Project: Camel
          Issue Type: Bug
    Affects Versions: 3.7.0
            Reporter: Antoine DESSAIGNE


Hello,

When trying to update from 3.6.0 to 3.7.0 we noticed a regression in the type converter system.

The following route no longer works
{code}
from("timer:foo?repeatCount=1").
setBody(constant(Map.of("a", "A", "b", "B"))).
convertBodyTo(Collection.class).
split(body()).log("${body}");
{code}

I used to find the converter {{org.apache.camel.converter.CollectionConverter#toSet(java.util.Map<K,V>)}} but now it throws the following exception
{noformat}
Caused by: org.apache.camel.NoTypeConversionAvailableException: No type converter available to convert from type: java.util.ImmutableCollections.MapN to the required type: java.util.Collection with value {a=A, b=B}
	at org.apache.camel.impl.converter.CoreTypeConverterRegistry.mandatoryConvertTo(CoreTypeConverterRegistry.java:275)
	at org.apache.camel.support.MessageSupport.getMandatoryBody(MessageSupport.java:115)
	... 11 more
{noformat}

Can you have a look? Thank you very much
