The following simple expression doesn't behave the same way whether it's used as expression or predicate:
{noformat}
'{{foo}}' == 'bar'
{noformat}

When used in a predicate the given expression is thrown:
{noformat}
org.apache.camel.language.simple.types.SimpleIllegalSyntaxException: functionEnd has no matching start token at location 7
'{{foo}}' == 'bar'
       *
