Sorry for the delay testing the fix... It's been a busy couple of weeks.
So I checked out the code from svn trunk today (05-22-08) and tested it. With
the test case I provided, everything was good... However when I tested it with
a more thorough test case (EG: a real web application :) ), i ran into some
crashes implying I was using an the OLD classloader.
It seems like the Thread that is calling the init() function has the *wrong*
classloader attached to it (EG: the old servlet's class loader, instead of the
new one). I've narrowed down the issue (this... took some time :) ) and have a
new test case for you.
Just replace the ServletRestartTest.war file with this new one (and re-extract
it). There are now two classes, the ServletRestartTest servlet itself, and
another class (it happens to be blank) that I will try to load using the
Classloader.
Do the same test as before... run:
ab -c 10 -n 100 http://localhost:8080/ServletRestartTest/ServletRestartTest
then query the reload by going to this url at the same time:
http://localhost:8080/manager/reload?path=/ServletRestartTest
You'll see this:
