Description everflux 2015-03-28 16:47:52 UTC
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)
Comment 1 Martin Entlicher 2015-04-03 15:28:40 UTC
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.
Comment 2 everflux 2015-04-03 16:29:14 UTC
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...
