How to check if a (possibly obfuscated) class exists without displaying in logs

I am trying to check if a class exists at runtime.

Usage is Class.forName( "com.class.Name" );

not an option, as the class I want to test might be obfuscated using proguard.

Another option is to use a block try-catch(NoClassDefFoundError)

and try to access the actual class, but this results in the following logs:

• art: Rejecting re-init on previously-failed class
  
  in newer os versions with ART - which I was able to avoid by executing Class cls = CheckedClass.class
  
  surrounded by a try-catch
  
  different method.

• dalvikvm: Could not find class...
  
  on older os versions using dalvik which I haven't figured out yet how to avoid. Any thoughts?
