Fixes [CAMEL-24651](https://issues.apache.org/jira/browse/CAMEL-24651): regression introduced by commit f9048eb0a822 ("consolidate duplicated code for printing the stack traces"). ## Problem When `${exception.stacktrace}` is evaluated on an exchange that has no exception: 1. `LanguageHelper.exceptionStacktrace()` calls `exception(exchange)` which returns `null` 2. That `null` is passed to `ExceptionHelper.stackTraceToString(null)` 3. `stackTraceToString()` calls `e.printStackTrace(printWriter)` → **NPE** Prior to the refactoring, the call site had an explicit null check that was lost during consolidation. `LanguageHelper.exceptionMessage()` still has its null guard and is unaffected. ## Fix Add a null guard at the top of `ExceptionHelper.stackTraceToString()` so it returns `null` when the supplied `Throwable` is `null`. This is the defensive approach: it protects all callers rather than just the one in `LanguageHelper`. ## Test Added `SimpleTest#testExceptionStacktraceNoException` to cover the regression: evaluating `${exception.stacktrace}` on an exchange with no exception must return `null` (not throw NPE). -- This is an automated message from the Apache Git Service.
