Description

While investigating an issue I found some circumstances where invalid log placeholders are present. They would cause the log messages to be printed like this:

Error message: {}

It's a minor issue, but could be confusing for debugging.

 

Here's one example: https://github.com/apache/camel/blob/4ea9e6c357371682b855d2d79655b41120331b7a/core/camel-xml-jaxp/src/main/java/org/apache/camel/converter/jaxp/XmlConverter.java#L1005 

 

The last item, the exception object, will not be displayed. Instead, the stackTrace will be printed and the {} will be shown on the message.

 

This also happens on 3.4.3.
