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!

Answer 1

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.

Similar problem here with IntelliJ and JBoss. For me, there were JAVA_OPTS specified in standalone.conf containing jdwp configuration. Commenting this out lead me to be able to debug from IntelliJ.

Maybe this helps other searching for this phrase, because there's not much info around on the internet.
