--ignore-signing-information do not suppress all errors

[Remi Forax]

Hi all,
I wonder if it's an issue or if there is a rational for not suppressing this error when using --ignore-signing-information.

I'm patching the compiler related modules of the jdk9 with the one from amber/langtools, so i know that i'm doing something borderline but i gently ask jlink to do not bother me with the hash signature.

...
