Remove headers behaves differently and not as expected

Hi guys,
              I tried to work with the camel's remove header which works for
some and does not work for other patterns

It works for the below patterns

<removeHeaders pattern="*" />
<removeHeaders pattern="CamelFile*" />

It does not work for 
<removeHeaders pattern="*File*" />

Is the above expected?

Also in the exclude pattern I observe that the wildcard patterns * is not
recognised at all. 

eg.<setHeader headerName="firstCustomHeader">
				<constant>firstCustomHeader</constant>
			</setHeader>
			<setHeader headerName="secondCustomHeader">
				<constant>secondCustomHeader</constant>
			</setHeader>
			<setHeader headerName="thirdCustomHeader">
				<constant>thirdCustomHeader</constant>
			</setHeader>
			<setHeader headerName="fourthCustomHeader">
				<constant>fourthCustomHeader</constant>
			</setHeader>
                       
                       <removeHeaders pattern="*"
excludePattern="fourth*|third*" />
the above removes all the header but does excludes the excludePattern value

<version>2.13.1</version>


Thanks,
Naveen Raj

Hi

Yes either use a regular expression or use a single * in the end as
wildcard. So *File* is not valid. Use a regular expression for that.
