RFR: 8245036: DataInputStream.readFully(byte[], int, int) does not throw expected IndexOutOfBoundsExceptions

[Brian Burkhalter]

Also, instead of using the boolean “caughtException,” we usually just put, e.g., the throwing of the RuntimeException on the line after where the IIOBE or whatever would be thrown. I don’t think the “finally” block is necessary.

Thanks,

Brian
