    @pnowojski I've tried but it seams it's hard to do this. The class loader can not be accessed out of the class. @GJL any suggestion? Or need to test?

> The user code ClassLoader is not set as the context ClassLoader for the thread invoking {{ProcessingTimeCallback#onProcessingTime(long timestamp)}}:
> https://github.com/apache/flink/blob/84a07a34ac22af14f2dd0319447ca5f45de6d0bb/flink-streaming-java/src/main/java/org/apache/flink/streaming/runtime/tasks/StreamTask.java#L222
> This is problematic, for example, if user code dynamically loads classes in {{ProcessFunction#onTimer(long timestamp, OnTimerContext ctx, Collector<O> out)}} using the current thread's context ClassLoader (also see FLINK-8005).
