Incorrect caching type converter misses for NaN
-----------------------------------------------
Key: CAMEL-4959
URL: https://issues.apache.org/jira/browse/CAMEL-4959
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.8.3
Reporter: Andrey Utkin
When converting Double or Float with value NaN,
org.apache.camel.converter.ObjectConverter returns "null". But
org.apache.camel.impl.converter.BaseTypeConverterRegistry.doConvertTo(Class,
Exchange, Object) interpret this "null" as "suitable conversion not found" and
cache misses. This lead to completely forgetting of conversion for given types.
For example, when conversing Double to Long, all works until Double is NaN.
After that, conversion for "Double-to-Long" marked as misses. And camel stop
do any conversion for Double-to-Long until restart.
Possible solution is to modify ObjectConverter`s methods to return "Void.TYPE"
instead of "null" for NaN.
