getRootCause

public Throwable getRootCause()

Returns the inner-most CannotProvideCoderException when they are deeply nested.

For example, if a coder for List<KV<Integer, Whatsit>> cannot be provided because there is no known coder for Whatsit, the root cause of the exception should be a CannotProvideCoderException with details pertinent to Whatsit, suppressing the intermediate layers.
