Alternatively maybe its toString could be changed to drop the index (I would need to dig into the history to find out if there is really any use for the index in the String representation).

In case their answer is a yes, I'll work on implementing the suggestion to return the name as String. Shall I maybe do the zipfs change in a different PR then? The more important change in the context of javac is printing out the jar name in javac itself.

Good catch, I pasted two times the error message after the proposed patch. Fixed.

I've factored out the zipfs change into #8655. So this change only affects javac now.
