Compiler creates broken classfiles although errors are shown in output

[Sven Reimers]

Due to missing interface classfiles wrong contents is generated (not
illegal),  e. g. An instance of fails n case of missing transitive
interface which is ok if interface is available at compilation time.

It seems (I believe)  the exit code is 0..

If necessary I will try to get more details and slimmed down example code.

Thanks
