Propagates {@code throwable} exactly as-is, if and only if it is an instance of {@code
declaredType}. Example usage:

<pre>
try {
someMethodThatCouldThrowAnything();
} catch (IKnowWhatToDoWithThisException e) {
handle(e);
} catch (Throwable t) {
Throwables.propagateIfInstanceOf(t, IOException.class);
Throwables.propagateIfInstanceOf(t, SQLException.class);
throw Throwables.propagate(t);
}
</pre>

@deprecated Use {@link #throwIfInstanceOf}, which has the same behavior but rejects {@code
null}.
Propagates { @code throwable } exactly as - is if and only if it is an instance of { @code declaredType } . Example usage :
