After making the switch from Java 7 to Java 8, and from proguard 4.9 to 5.0beta2, I can no longer optimize my project due to the error mentioned in the title.
I did not find a way to get the actual exception stack, if you like to enlighten me :-)
The maybe relevant program output looks like this:
~~~~Note: there were 1 references to unknown classes.
You should check your configuration for typos.
Note: there were 3 unkept descriptor classes in kept class members.
You should consider explicitly keeping the mentioned classes
Note: there were 4 unresolved dynamic references to classes or interfaces.
You should check if you need to specify additional program jars.
Note: there were 11 accesses to class members by means of introspection.
You should consider explicitly keeping the mentioned class members
(using '-keep' or '-keepclassmembers').
Ignoring unused library classes...
Original number of library classes: 44120
Final number of library classes: 44120
Printing kept classes, fields, and methods...
Removing unused program classes and class elements...
Original number of program classes: 4692
Final number of program classes: 4163
Method must be overridden in [proguard.optimize.DuplicateInitializerInvocationFixer] if ever called~~~~
