Description

The following simple expression doesn't behave the same way whether it's used as expression or predicate:

'{{foo}}' == 'bar'

When used in an expression, it works perfectly.

When used in a predicate the given expression is thrown:

org.apache.camel.language.simple.types.SimpleIllegalSyntaxException: functionEnd has no matching start token at location 7
'{{foo}}' == 'bar'
