Google Appengine and rx-Java?

google-app-engine, rx-java

Solution

The problem is the limitation of Java Threads in Google Appengine: https://developers.google.com/appengine/docs/java/#Java_The_sandbox

RxJava uses Java `Thread` and `Executor` in the `Scheduler` implementations. So the codes which get involved some concurrent `Scheduler`s can not run in Google Java Sandbox.

If you want to use `Scheduler` in Google Appengine, you need to implement a special `Scheduler` by yourself. Besides, some operators may use `Scheduler` by default, such as `delay` use `Schedulers.computation()` by default. Remember to use their `Scheduler` overload methods.
