[OpenJDK 2D-Dev] [9] request for review: 8074954: ImageInputStreamImpl.readShort/readInt do not behave correctly at EOF

[Andrew Brygin]

Hello,

  could you please review a fix for CR 8074954?

Bug: https://bugs.openjdk.java.net/browse/JDK-8074954
Webrev: http://cr.openjdk.java.net/~bae/8074954/9/webrev.00/

  The problem happens if an input stream does not contain enough data
  to read a multi-byte type (as 4-bytes integer or 2-bytes short)
  completely. In this case the actual number of obtained bytes is
  returned, and if we get at least one byte, the EOF exception in
  not triggered.
  As a result, an incorrect value is returned.

  Suggested fix is to check explicitly whether required number of bytes
  has been read.

  Supplied regression test demonstrates the problem.

  Please take a look.

Thanks,
Andrew.
