Not all third-party libraries can be used with App Engine Java standard runtime, due to the limitations imposed by the sandbox <https://cloud.google.com/appengine/docs/standard/java/runtime#threads>. If the library will accept a ThreadFactory <https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ThreadFactory.html>, you can pass it one that you get from com.google.appengine.api.ThreadManager.currentRequestThreadFactory() <https://cloud.google.com/appengine/docs/standard/java/javadoc/com/google/appengine/api/ThreadManager#method-detail>. Otherwise, the library will need to be modified in such a way as to make use of App Engine's ThreadManager.
