I am running IDEA 9 attempting to debug our web app via Tomcat 5.5 running within the IDEA environment. Running the app works fine; however, all attempts to debug in this configuration fails with the above error message (which can only be seen once I end the debug session.) All breakpoints are ignored.
I have tried running with Java 1.4 and Java 1.5. I can get debugging working properly with Tomcat 4.
Any ideas or suggestions as to what might be going on? (Note I have rebooted, as well as tried the shared memory option for the debugger -- neither worked).
