I have a maven based web application, deployed in tomcat, that is running under netbeans debugger. After adding a method I got the message "The debugger does not support Hot Fix action. details: add method not implemented". A redeploy is happening then. After clicking 'ok' and performing code changes inside a different method, this time not adding a new method, the warning appears again. After restarting the debugging session the same edit does not yield the warning dialog, but a redeploy happens nevertheless. (This may be intended by deploy-on-save)
It's better to use redeploy then hotfix, since the hotfix has limitations. Hotfix always tries to redefine the whole class, therefore when you add a method, then even when you make further changes to method bodies, the added method is a part of the class that is being redefined. The redefinition logic is implemented in the debugger backend in JDK.
The error message should not appear on every change in the same debugging session when problematic situation is resolved by a redeployment. (In this case netbeans triggers a redeploy after the user clicked ok. All future changes trigger the warning, this time without redeployment, again.)
O.K. I'll check the behavior...
