List of usage examples for org.apache.commons.lang3.exception ExceptionUtils getRootCause
public static Throwable getRootCause(final Throwable throwable)
Introspects the Throwable to obtain the root cause.
This method walks through the exception chain to the last element, "root" of the tree, using #getCause(Throwable) , and returns that exception.
From version 2.2, this method handles recursive cause structures that might otherwise cause infinite loops.
