Description

Filtering on a header that contains a string with a hyphen, the following works:

from(file://temp).filter(header(FileComponent.HEADER_FILE_NAME).matchesRegex(".-.")).to("mock:result");

but contains is more natural and should also work.

from(file://temp).filter(header(FileComponent.HEADER_FILE_NAME).contains("-")).to("mock:result");

It does not as contains() is focused on collections and reduces to checking equality on single values. A string specialisation could use string.contains.
