I can't see any reason why you can't use static variables.

Just make sure that the variable is thread safe, as multiple threads 
will be accessing it concurrently.

 From looking at your code. Imagine 2 threads call your setter function, 
then call the test() function. One of the threads will be using the 
incorrect String (I guess?). So in this case using static variables 
would probably produce unexpected results!
