Umm, no actually. I think it should be allowed anywhere. For a file appender it would look pretty crap anywhere else, but for Chainsaw as an example, this is the Pattern Layout conversion I am using for the detail panel, and it works a treat... (mind you I am only showing a single event at a time):
Level%p
Logger%c
TIme%d
Thread%t
Message%m
Location%l
NDC%x
MDC%X
Class%C
Method%M
Line%L
File%F
PropertiesProperties support is missing from PatternLayout at this time, stay tuned.
ThrowableThrowable Information support is missing from PatternLayout at this time, stay tuned
Paul, while I agree that generally speaking %T need not always be at the end, even in your usage case Throwable is shown last. However, there is an interesting case where the use wants to override the way the stack trace is printed. For example when she wants nested exceptions to be printed too...
In conclusion, let us add %T (or %exception, %throwable). I'll also change PatternLayout to keep track of the of the PattenConverters that handle exceptions and adjust ignoresThroable accordingly. I'll work on Joran and come back to this issue later. Please remind me if I forget.
