public static void rethrowSafely(java.lang.Throwable t,

                          throws java.lang.Throwable

Rethrows the given Throwable in a manner designed to avoid UndeclaredThrowableException's. If the given Throwable is an Error or RuntimeException, it is simply rethrown. Else its type is checked for assignment compatibility with the classes given by acceptableTypes. If it is type compatible, it is rethrown; else it is wrapped in a NestableRuntimeException which is then thrown.

Typically this method would be used for rethrowing exceptions caught inside an invocation handler's invoke() method.

Throws:

java.lang.Throwable
