Simple language - OGNL - Invoking explicit method with no parameters should not cause ambiguous exception for overloaded methods

If you want to invoke a method on a bean which is overloaded, such as a String with toUpperCase having

• toUpperCase()
• toUpperCase(Locale)

Then if you specify this in a simple ognl expression as follows

${body.toUpperCase()}

Then Camel bean component should pick the no-parameter method as specified.
