ParameterizedType proguard runtime error

My code works in debug mode (not proguard)

My code

```
public static ResponseServer generateJSON(String json, Class dataClass){
ResponseServer responseServer = null;
if (dataClass == JUnidade.class)
responseServer = (ResponseServer)LoganSquare.parse(json, new ParameterizedType>() { });
....

```

my rules of proguard-rules.pro

```
-keep class com.mypackage.myapp.WebService.Models.ResponseServer.**

-keep class * extends com.bluelinelabs.logansquare.ParameterizedType.**

-keepclassmembers class com.mypackage.myapp.WebService.Models.** {*;}

-keep public class com.mypackage.myapp.WebService.Models.** {
public static ;
}
```

Decompiled in debug mode (not run proguard) It's Work


Decompiled in release mode (run proguard) don't work


any suggestion?

My question in [stackoverflow](http://stackoverflow.com/questions/38920279/runtime-error-in-generic-method-with-proguard)

Start with the generateJSON method and the rules in proguard-rules.pro, then compare the debug and ProGuard release behavior described in the issue. Reproduce the runtime failure in a release build and verify that the ParameterizedType-based LoganSquare parsing works there without the reported error.
