Eclipse 3.5.2 Does Not Hit Breakpoints when Remote Debugging on Tomcat 6»

This is a local-to-local debug setup, from an Eclipse instance to Tomcat on localhost.

I've tried starting tomcat from both /etc/init.d/tomcat6 start and from /usr/share/tomcat6/bin/catalina.sh jpda start (ie from the startup command and from CATALINA_HOME command), no change in result.

The JAVA_OPTS to Tomcat are

JAVA_OPTS="-Djava.awt.headless=true -Xmx256m -XX:+UseConcMarkSweepGC -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,address=8888,server=y,suspend=n"

Eclipse project is a simple Scala Lift (2.8.1/2.3) web project generated from the default Lift Maven archetype (this has worked in debug before, so it's not the archetype's fault).

Eclipse Remote Debugging configuration is default, except port changed to 8888. Source path includes project directory.

Maven is used for build/deploy, so a mvn clean and mvn tomcat:redeploy is done after breakpoints are set.

Remote Debug session is launched, connects to Tomcat as seen in screenshot.

Tomcat does seem to be in debug mode, as evidenced by catalina.out:

Web site is accessed with browser on the normal Tomcat URL (eg http://localhost:8080/test/cleanproject).

No breakpoint is ever reached.
