public class My|Impl implements IFoo { //invoke Fix Code at caret |

ACTUAL: no hint which allows you to generate all methods which have to be implemented. There is an exception in the log

EXPECTED: hint which allows you to generate all methods which have to be implemented.

Comment 1 Svata Dedic 2015-02-27 09:22:16 UTC 
Sorry I could not reproduce the defect using 8.0.2; the hint to implement all abstract methods appeared and its fix generated the method properly.

public class Bug implements Callable {
..

Could you attach the whole file, please ? Does the implemented interface exist ? if so, could you please attach the interface, too ?
