if we do something like this:
{code:java}
String helloMessage = "HelloWorld " + someclass;
logger.info(helloMessage);{code}
the toString() method of SomeClass will be called only once
if we use the $ notation,
{code:java}
String helloMessage = "HelloWorld $someclass";
logger.info(helloMessage);{code}
the toString() method will be called 13 times for this example and it is
variable depending of the numbers of characters of the toString() method ...of
SomeClass
For classes with big toString() implementations we had over 30 seconds for such
a log call
