ClassNotFoundException on com.sun.tools.jdi.SocketTransport when Debugging

This is based on this thread:
http://intellij.net/forums/thread.jspa?messageID=3540694??

Copying the tools.jar from the /lib directory to the ]]>/jre/lib directory did not work for me. I am still getting the ClassNotFoundException on the com.sun.tools.jdi.SocketTransport class when trying to debug my app. This is in IDEA 4.5.4 (build 2253) on Linux (2.6.15-1.2054_FC5 (x86_64)).

Does the tools.jar have to be from a 1.4.x distribution?

I should also mention that the JRE isn't the "official" one shipped with IntelliJ. My "jre" folder in the IntelliJ installation directory is a soft link to a 64-bit 1.5 JDK:

lrwxrwxrwx 1 jbrutto jbrutto 21 May 2 11:21 jre -> /jdks/64/jdk1.5.0_06/
