Description

If the cause of a RemoteException is PathIOException, RemoteException's unwrapRemoteException methods would fail, because some PathIOException constructors initialize the cause to null, which makes Throwable to throw exception at

    public synchronized Throwable initCause(Throwable cause) {
        if (this.cause != this)
            throw new IllegalStateException("Can't overwrite cause");
