>             Project: Camel
>          Issue Type: Bug
>          Components: camel-spring-boot
>    Affects Versions: 2.17.0, 2.17.3, 2.18.0

> conflict running simple expression w/ list under spring boot.  SpringTypeConverter is
registered as a fallback converter which gets picked up during ognl while attempting to convert
list -> map causing an exception instead of a null response that is expected.  It is happening
under 2.17 & 2.18.
