I am to see an Isabelle extension in action.

In $ISABELLE_HOME/etc/options, I have set

public option ML_debugger : bool = true

I have rebuilt HOL:

isabelle build -f -b HOL

I opened my theory file containing the Isabelle/ML parts, and the theory file containing the use of the extension, in the same Isabelle/jEdit window. Still when I set a breakpoint, fiddle with the extension using theory, point the cursor where the new construct is, trying to run the Debugger with Continue to the breakpoint, nothing happens.

What else do I need to run the Debugger properly in this setting?
