public class RealtimeAllocationError

Thrown out of a RealtimeTask’s cycle() when the cycle allocates beyond its budget (RealtimeParameters.setAllocationBudget(int), zero unless set).

It ends the steady state: the thread delivers it to RealtimeTask.failed(Throwable) and stops. The message names the class whose allocation was refused. The build rejects the allocations it can see, so this one came from a path the check cannot follow – a call through an interface or a method overridden in several classes.
