> Hey, in one of my SourceFunctions, I'm calling 
> ServiceLoader.load(MyDefiniedService.class) which internally fetches the 
> ClassLoader by calling Thread.currentThread().getContextClassLoader(). It 
> seems like whichever ClassLoader this fetches is unaware of any jars/code 
> that I've shipped.
> My application code has not changed and this came up in my attempt switch 
> planners from the old planner to the blink planner. Would appreciate any help 
> I can get on this, thanks.
