ProGuard - Obfuscating apk causing error

问题

I am having issues with my app once I obfuscate the code with ProGuard. The app launches ok, but once I try to make a REST call to my server, I get the below error in the LogCat.. and the app just hangs.

Exception Ljava/lang/NullPointerException; thrown while initializing Lorg/codehaus/jackson/map/introspect/VisibilityChecker$Std;

Any help is appreciated.. as I have searched the entire internet :|

Below is my pro guard .cfg contents:

    -optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-dump class_files.txt 
-printseeds seeds.txt
