Substring problems with simple language

[Stefan Ziegler <st...@gmail.com>]

Hi

I try to substring the file name and set it as property:
from("file://"+pathToUnzipFolder+"/?noop=true&charset=ISO-8859-1&include=.*\\.itf&delay=30000&initialDelay=2000&readLock=changed")
.setProperty("dataset", simple("${header.CamelFileName.substring(2,4)}"))
.process(new Ili2pgReplaceProcessor());

This works with Apache Camel 3.0.0.RC3 and Spring boot but fails with
Quarkus which uses the same version (as far as I see):

java.lang.IllegalArgumentException: Failed to set property bean on null.
Reason: java.lang.NullPointerException
