Bean instance is null. OGNL bean expressions requires bean instances.

Hello,

Running Camel 2.16.1, I am trying to invoke a static method as follows:

<setHeader headerName="SCMS_MATCH_FILE_NAME">
	<method 
			beanType="org.apache.camel.util.StringHelper"
			method="removeLeadingAndEndingQuotes(${header.If-None-Match})"
	 />
</setHeader>


However I get an exception with this message:

Bean instance is null. OGNL bean expressions requires bean instances.

Any idea why?

Thanks and best regards,
Alex soto

It was not designed primary to call utility methods, but methods on
your existing message body and headers - where there is an instance.

You are welcome to log a JIRA ticket to see if we can adjust it to use
static methods only.
