public abstract class ControlFlowError
extends Error

A Error that is used to regulate control flow inside multiverse, to be more specific jump from code to the handler the transaction management logic (instrumented or SpeculativeConfigurationFailure) so it doesn't indicate a bad thing.

Normally it would be a very bad thing to regulate control flow using an exception/error, but to make seamless integration in the Java language possible, there is no better alternative. So you should not catch these exceptions unless you really know what you are doing.

It is an Error instead of a RuntimeException, to prevent users trying to catch the error inside a try/catch(RuntimeException) block and consuming important events like a ReadConflict or a WriteConflict. In most cases these events can be solved by retrying the transaction.
