I would like to use ignorably as the adverb of ignorable but I am not sure whether this is correct. I did not find ignorably in any online dictionary.
To give the context: Normally, you cannot ignore a thrown exception in programming: You are forced to handle it if you want to make you program work correctly. I have a method that does something similar to throwing an exception but you are not forced to handle it immediately. So my question is whether the following sentence is possible: An exception was thrown ignorably.
