I'm trying to bind a jar library (jCIFS) on MFA, but i'm stuck on some errors, like this one:

'Jcifs.Util.MD4' does not implement inherited abstract member 'Java.Security.MessageDigestSpi.EngineDigest()

After some research, i found some topics about this, telling to edit the metadata to change the permissions of the classes, like this:

<attr path="/api/package[@name='java.security']/class[@name='MessageDigestSpi']/method[@name='engineDigest']" name="visibility">public</attr>

But the error didn't change, and a still won't get what this error means.

Anyone ? Thanks.
