Subject Re: A default getLogger method

Hi Brian,

>From the javadoc for Thread getStackTrace():

"Some virtual machines may, under some circumstances, omit one or more stack
frames from the stack trace.  In the extreme case, a virtual machine that
has no stack trace information concerning this thread is permitted to return
a zero-length array from this method.".

Hard to see a workaround for that, if it can/does happen.
