This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
The ImplementationProvider class is deprecated; but there is no public replacement: EditorImplementationProvider mentioned in @deprecated tag resides in a closed package. The actual need is getting glyph gutter actions. This in turn is needed to delegate control to other actions (see code in java.editor/src/org/netbeans/modules/java/editor/overridden/IsOverriddenAnnotationAction.java, cnd.navigation/src/org/netbeans/modules/cnd/navigation/overrides/OverrideAnnotationAction.java)
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue. Thanks for your cooperation, NetBeans IDE 8.2 Release Boss
