# Description `SimpleFunctionExpression` shares the same `Map<String, Expression>` cache instance with the expression-level cache (`SimpleExpressionParser`, `SimplePredicateParser`). Without key namespacing, a function name like `body` could collide with any other entry stored under the same string, causing the wrong `Expression` to be returned silently. This commit introduces a `@FUNC@` prefix constant in `SimpleFunctionExpression` and applies it on every cache read and write. The prefix is intentional: `@` is not a valid character in a Simple function name, so `@FUNC@body` can never collide with any expression-level key. This issue was discovered during the work on CAMEL-22894. # Target - [x] I checked that the commit is targeting the correct branch (Camel 4 uses the `main` branch) # Tracking - [x] If this is a large change, bug fix, or code improvement, I checked there is a [JIRA issue](https://issues.apache.org/jira/browse/CAMEL-23800) filed for the change (usually before you start working on it). # Apache Camel coding standards and style - [x] I checked that each commit in the pull request has a meaningful subject line and body. - [x] I have run `mvn clean install -DskipTests` locally from root folder and I have committed all auto-generated changes. _Claude Code on behalf of Adriano Machado_ -- This is an automated message from the Apache Git Service.
