You have to use IJ.handleException(e); to show that log window.

You have to implement that yourself: create a new FileOutputStream, then
pass that to the constructor of a PrintStream, and then use the
Exception#printStackTrac(PrintStream) method:

You also want to make sure that the part of your plugin's documentation
people actually read contains a big notice that they need to provide you
with the stack trace (i.e. log file) when they report bugs. It is often
forgotten that reporting bugs without providing enough information to make
heads or tails of the problem makes it hard to help.
