This error indicates that you have invoked an interface method not annotated with @ThreadSafe from a thread-safe context (e.g., code that uses locks or is marked @ThreadSafe). The fix is to add the @ThreadSafe annotation to the interface or to the interface method. For background on why these annotations are needed, see the detailed explanation here.
