findCause

@SafeVarargs
public static <T extends Throwable,C extends Class<? extends T>> T findCause(Throwable root,
                                                                                          C... ofClasses)

Search the cause chain of t (starting from and including t) for a Throwable that is assignable to any of ofClasses, or null if not found. The chain is first fully searched for the first of C, then second, etc.

Type Parameters:

T - This should be figured out by the compiler: the lowest common ancestor of ofClasses.

C - Should be figured out by the compiler too.

Parameters:

ofClasses - Throwable classes in order of priority to be searched for.

root - The cause from which the search is to be started.
