JSApplicationCausedNativeException

A special RuntimeException that should be thrown by native code if it has reached an exceptional state due to a, or a sequence of, bad commands.

A good rule of thumb for whether a native Exception should extend this interface is 1) Can a developer make a change or correction in JS to keep this Exception from being thrown? 2) Is the app outside of this catalyst instance still in a good state to allow reloading and restarting this catalyst instance?

Examples where this class is appropriate to throw:

• JS tries to update a view with a tag that hasn't been created yet
• JS tries to show a static image that isn't in resources
• JS tries to use an unsupported view class

Examples where this class **isn't** appropriate to throw: - Failed to write to localStorage because disk is full - Assertions about internal state (e.g. that child.getParent().indexOf(child) != -1)
