-----------------------------------

             Summary: simple - ${properties:key:default} with a default containing an operator word is parsed as a predicate
                 Key: CAMEL-24963
                 URL: https://issues.apache.org/jira/browse/CAMEL-24963
             Project: Camel
          Issue Type: Sub-task
          Components: camel-core
            Reporter: Claus Ibsen
            Assignee: Claus Ibsen
             Fix For: 4.23.0


Regression from CAMEL-24921 (edb3a1406c60, predicate inside ${ }). SimpleFunctionExpression runs the operatorsOutside check before any function factory; it skips a match when parentheses are open or quotes appear before the operator word, but not when the word is inside a property default value or inside brackets.

* (verified) {{${properties:msg:value is not set}}} now fails with "Binary operator is does not accept not on the right hand side". Before it returned the default value "value is not set".
* likely the same: {{${header[order in progress]}}}

Fix: skip the predicate-in-braces detection for function text such as properties defaults / bracket keys, and add tests.
