Exceptions: an exception thrown from finally replaces the exception thrown from try

When both the try block and its finally block throw, the finally block's exception is the one that actually propagates to the caller; the original exception from try is discarded unless it was explicitly attached first.

Code

try {
    try {
        throw new RuntimeException("from try");
    } finally {
        throw new IllegalStateException("from finally");
    }
} catch (Exception e) {
    System.out.println("Propagated: " + e.getClass().getSimpleName() + ": " + e.getMessage());
}

Output

Propagated: IllegalStateException: from finally
