Fix for performance issue in RxJava 1.0.3+

YourApp.java

// Issue: https://github.com/ReactiveX/RxJava/issues/3119
class YourApp extends Application {
  static {
    // I recommend you to put this code into static initialization block of Application class
    // because Application class will be loaded before you will start doing some work via RxJava
    
    // PLEASE add comment "remove fix from app class… when you'll switch to new version of RxJava"  
    // near to "compile 'io.reactivex:rxjava:1.0.13'" in your build.gradle
    System.setProperty("rx.scheduler.jdk6.purge-force", "true");
    
    // Please read changelogs of new RxJava releases and remove this workaround when problem will be fixed
    // I hope fix https://github.com/ReactiveX/RxJava/pull/3121 will be merged into RxJava 1.0.14
    
    // Notice, this issue also affects non-Android systems: backends, etc, 
    // because RxJava 1.0.13 does not cache reflection call. You can apply this to your backend apps too.
  }
}
