Description Jesse Glick 2013-12-06 21:19:22 UTC 
Product Version = NetBeans IDE Dev (Build 20131206-3422eed6fdbf)
Operating System = Linux version 3.8.0-34-generic running on i386
Java; VM; Vendor = 1.7.0_45
Runtime = Java HotSpot(TM) Client VM 24.45-b08

Started seeing this error recently in dev builds after declaring a class to extend an abstract supertype. The usual hint to implement the abstract methods (which are all protected, certainly accessible) is not shown, only this error.

After some time passes, or I click around enough, or something (?), the expected hint to implement the abstract methods does eventually appear, and works when accepted.

Workaround: Alt-INSERT, Implement Method, click top (class name) checkbox, accept dialog.

Works for me - at least on a simple case. Please post code fragments, which produce the error on your site; thanks.

I had this issue.

The subclass was in the wrong package. When I moved it to the same package as its parent class, the bug went away, and I was able to implement the abstract methods normally.

It is still a bug, as the error message is misleading and likely to waste the user's time and mental energy. Any fixes would be much appreciated. I hope this helps.
