Smooks failed to filter source - java.lang.NoSuchMethodError: sun.misc.Unsafe.defineClass(Ljava/lang/String;[BII)Ljava/lang/Class

I am relatively new to EDIFACT/D96A. I am trying to convert from edi using the D96AInterchangeFactory.

Here is what i have:

D96AInterchangeFactory factory = D96AInterchangeFactory.getInstance();
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(ediContent.getBytes());
UNEdifactInterchange interchange = factory.fromUNEdifact(byteArrayInputStream);

on this I get the following error:

I read and also added a dependency in d96a for mvel2 and version 2.2.0.Final. Still the same error pops up.

Using JAVA 8 What might i be doing wrong? Thanking you in advance.

Bumped up the mylin dependency from 1.6 to 1.7.0 works now
