Using RMI - RetroGuard Documentation
As with serialization, remote method invocation (RMI) has some subtleties.
A good starting point is the tutorial at Sun.
To preserve the necessary classes, methods, and fields for RMI to work
correctly after obfuscation, add a script line:
.option RMI
This is exactly equivalent to the script lines:
.option Serializable
.class ** protected extends java/rmi/Remote
.class **_Stub
.class **_Skel
So, in addition to all the preservations needs to pass serialized objects
using RMI, the RMI 'stubs' and 'skeletons' are preserved, along with any
classes that implement Remote and the public and protected methods and fields
in those Remote classes.
With this RMI option in place, it is even possible for communication to
occur between an obfuscated RMI client and an non-obfuscated RMI server.
