Reads all the bytes from a file. The method ensures that the file is closed when all bytes have been read or an I/O error, or other runtime exception, is thrown.

Note that this method is intended for simple cases where it is convenient to read all bytes into a byte array. It is not intended for reading in large files.

Parameters:

path the path to the file

Returns: a byte array containing the bytes read from the file

Exceptions:

IOException     if an I/O error occurs reading from the stream

OutOfMemoryError     if an array of the required size cannot be allocated, for example the file is larger that 2GB

SecurityException     In the case of the default provider, and a security manager is installed, the checkRead method is invoked to check read access to the file.

`IOException`		if an I/O error occurs reading from the stream
`OutOfMemoryError`		if an array of the required size cannot be allocated, for example the file is larger that `2GB`
`SecurityException`		In the case of the default provider, and a security manager is installed, the `checkRead` method is invoked to check read access to the file.
