RuntimeException when implementing proguard with EventBus AsyncExecutor

[z0lope0z]

Hi! I'm not sure how to file reports and I'm not sure what's going on as well.
Basically, I'm currently implementing proguard in my project and this line of code fails:

...
 AsyncExecutor.builder().failureEventType(FailedEvent.class)
...

throwing the exception (here):

...
java.lang.RuntimeException: Failure event class must have a constructor with one parameter of type Throwable
    at de.greenrobot.event.util.AsyncExecutor.<init>(AsyncExecutor.java:104)
    at de.greenrobot.event.util.AsyncExecutor.<init>(AsyncExecutor.java:32)
...

unless I add

-keep class FailedEvent { *; }

to my proguard-rules.txt

If it's an expected behavior, should the best course of action be to include it in the wiki?

Right. Documented in 5619fea

Check updated https://github.com/greenrobot/EventBus/blob/master/HOWTO.md#proguard-configuration

Does it work for you?

Unfortunately current ProGuard config doesn't work for me:

-keepclassmembers class * extends de.greenrobot.event.util.ThrowableFailureEvent {
    <init>(java.lang.Throwable);
}

I still received below runtime exception:

java.lang.RuntimeException: Failure event class must have a constructor with one parameter of type Throwable

Changing above -keepclassmembers to below -keep class fixed it for me:

-keep class de.greenrobot.event.util.ThrowableFailureEvent { *; }

EventBus: 2.4.0
