I don't understand your objection. The logger does not log text strings, it logs messages with embedded expressions. Those expressions are evaluated. Your log message contained an invalid expression. This shouldn't throw an error, which is fixed. However, messages shouldn't contain invalid expressions. The fix is very simple - pass raw text data as arguments to the message, that the message itself. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4012621#...
