I have done some researching and was able to reproduce the problem by
removing junit.jar from my server side classpath .... However I did not
understand why it would not print the error message I had put in my code and
why the error would be on the call "ServletTestCaller caller = new
ServletTestCaller();" when ServletTestCaller does not make use of JUnit ...
!!
I think I have now understood ... Something a bit tricky it seems ...
What I understand is that although ServletTestCaller does not make use of
junit at all, it is loaded by the Tomcat WebappClassLoader. And it seems
that this loader actually makes a check at that point to verify that all
classes within it can be loaded ... So it will find that your test class
which makes use of Junit cannot be loaded ... This is the only way I can
understand it ... (I'll need to put the question to the Tomcat team or look
at the Tomcat code to verify that).
Here is the stack trace resulting from :
ServletTestCaller caller = null;
try {
caller = new ServletTestCaller();
} catch (Throwable e) {
logger.debug("an error", e);
}

This is a very strange behaviour in my opinion ...
I'll update the code to catch correctly the error and report it nicely ...
Thanks
