Fixed the message in Connector constructor in trunk in r1161322.
Backported to 7.0.x and will be in 7.0.21.
Regarding whether or not rethrow the exception from inside of Connector
constructor:
On one hand, such an error is nearly fatal. If I do not configure an Executor,
there are a lot of failures that follow. None of webapps is able to start
because of NPE in connector.getAttribute() call in
ApplicationContext.populateSessionTrackingModes() - stacktrace is below.
On other hand, Tomcat as a whole does start up and is manageable. There is
*.EXIT_ON_INIT_FAILURE system property that one can use to turn this into a
fatal failure.
If the ClassNotFoundException from Connector constructor were rethrown, the
startup sequence aborts immediately. It might be not what everyone wants.
I think this issue is sufficiently addressed. I do not intend to backport this
to 6.0.
