Cannot Launch a Java program in debug mode if the specified installed JRE is .../SDP70/jdk

Troubleshooting


Problem

Some users have not been able to launch a Java program in debug mode using IBM Rational Application Developer for WebSphere Software v7.0.0.x (which uses Eclipse 3.2.x), when the installed JRE preference is specified as: \SDP70\jdk (the default in v7.0) . The Java application launcher never starts the run/debug of the Java program.

Symptom

Attempts to Launch a Java program in debug mode in a Java project (see Related information item) the following message appears:


Could not rerun test
Cannot connect to VM
Reason:
Cannot connect to VM
OK / << Details
socket closed



and you get this console output:


JVMJ9TI002E Agent_OnLoad not found in library jdwp
JVMJ9VM015W Initialization error for library j9jvmti23(-3): JVMJ9VM009E J9VMDllMain failed
Could not create the Java virtual machine.
