Description John Williams CLA 2008-02-22 16:33:54 EST 
Created attachment 90518 [details]
A project that demonstrates the problem.

Build ID: M20071023-1652

Steps To Reproduce:
Put the following interfaces in separate files in a new project.  Clean the project.  Hilarity ensues.

interface A extends Iterable<B> {}
interface B extends C {}
inteface C extends A {}

More information:
The compiler reports the following two errors:

Cycle detected: a cycle exists in the type hierarchy between B and C
The hierarchy of the type C is inconsistent

This problem is dependent on the order of compilation.  If the classes are renamed so that they compile in a different order, the problem disappears.

I've tried this case with a recent build and it works fine.


Please try this case on a more recent build to see if you still detect a problem.
Comment 2 Kent Johnson CLA 2008-03-13 12:51:23 EDT 
Was able to reproduce in 3.3.2 but it works fine in the latest 3.4 build.

Closing as works for me.

Do not believe we'll be doing a 3.3.3 build.
