Works with Java8 but does not work with Java9

[Matioupi]

I'm using the sign.jar within https://github.com/Bin4ry/deejayeye-modder project;

On a distro with Java9 openjdk, I'm receiving an error about some sun.encoder.base64 (or something like that) class that does not exist.
I switch back to Java8 openjdk and it's working again.

That was more for the info than anything else.

I think appium is moving to using Google's apk signer instead of this jar.

https://developer.android.com/studio/command-line/apksigner.html

I'd recommend using that instead.
