if an error occurred while attempting to load the class; otherwise
null).

Throwable.getSuppressed()
Returns an array containing all of the exceptions that were
suppressed, typically by the
try-with-resources

Throwable |
Throwable.initCause(Throwable cause)

Thread.stop(Throwable obj)
Deprecated.
This method is inherently unsafe. See
Thread.stop()
for details. An additional danger of this
method is that it may be used to generate exceptions that the
target thread is unprepared to handle (including checked
exceptions that the thread could not possibly throw, were it
not for this method).
For more information, see
Why
are Thread.stop, Thread.suspend and Thread.resume Deprecated?. |
