[logback-user] Something which should be made clearer in the logback doc: Should a layout be threadsafe?

[jakartaman]

Hi,

Quick remark:

It is not clear from the logback docs whether a new layout should be 
threadsafe. I strongly suspect that it should be (why would logback do 
the possibly unnecessary locking for you?), but - should that not be 
explicitly said?

E.g. coders may fall into the usual trap of having an instance-bound or 
even static SimpleDateFormat member and not making the access to it 
synchronized etc (aehm).


Best regards,
