Can't debug Java project in IDEA IntelliJ 12

Question

On OSX w/Tomcat7 and IDEA IntelliJ 12.

The run configuration works fine. The debug configuration complains with:

    /usr/local/Cellar/tomcat/7.0.37/libexec/bin/catalina.sh run
    Error occurred during initialization of VM
    agent library failed to init: jdwp
    ERROR: Cannot load this JVM TI agent twice, check your java command line for duplicate jdwp options.
    Disconnected from server

I found this post from '11 but it's not helping.

The note about "once I removed it from system variables (inside the IDEA it is read only) problem was fixed" makes sense. So I tried removing this entire block from catalina.sh

    if [ -z "$JPDA_OPTS" ]; then
    JPDA_OPTS="-agentlib:jdwp=transport=$JPDA_TRANSPORT,address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND"
    fi

Didn't help. Any help would be greatly appreciated. Thanks!

Problem was catalina.sh was calling setenv.sh which was setting JAVA_OPTS like this:

    JAVA_OPTS="$JAVA_OPTS -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8000"

I don't know where this setenv.sh came from, as a co-worker's homebrew install of tomcat didn't have this file.

For now, I've configured IntelliJ debug to use catalina_idea_debug.sh, which is simply a copy of catalina.sh minus the call to setenv.sh. Works fine now.
