> Currently distributive contains com/google/protobuf package. Without proper shading client code could fail with:
> {code}
> Caused by: java.lang.IllegalAccessError: tried to access method com.google.protobuf.XXXX
> {code}
> Steps to reproduce:
> * create job class "com.google.protobuf.TestClass"
> * call com.google.protobuf.TextFormat.escapeText(String) method from this class
> * deploy job to flink cluster (usign web console for example)
> * run job. In logs IllegalAccessError.
> Issue in package protected method and different classloaders. TestClass loaded by FlinkUserCodeClassLoader, but TextFormat class loaded by sun.misc.Launcher$AppClassLoader
