Edson Tirelli commented on JBRULES-1152:
----------------------------------------

Michael, I don't think it is shadow facts related, but it is strange that the behavior changed from 4.0.0 to 4.0.1. 

Steve, if you can please provide us with a test case, we can dig and find out what is happening. 
One advise though: using dynamic beans as you are using is surely causing a performance hit on you, because each rule consequence is setting more than one attribute. I mean, dynamic beans will call update() automatically for each changed attribute, resulting in unnecessary calls. Also, this may explain why setting power button pressed to false has a better performance, since it is a boolean that is probably canceling a lot of activations at once, while setting the state is not canceling that many activations and eventually triggering a recursion.
You may want to take a look at using update() or using MVEL dialect modify call that will trigger all changes at once.

> Sorry, I don't have very specific information.  Some of my project's unit tests are hanging with drools 4.0.1.  No error, just not completing.  I tried to debug a bit but could not figure it out.  Consider this an early warning until I can gather more info.
> Everything worked fine with 4.0 so I went back to that.
