Review request for backport of JDK-8144131: ArrayData.getInt implementations do not convert to int32

[Hannes Wallnoefer]

Please review backport to 8u-dev of JDK-8144131: ArrayData.getInt 
implementations do not convert to int32:

http://cr.openjdk.java.net/~hannesw/8144131/webrev-8u/

This required manual merging of the import statements in 
NumberArray.java, otherwise the patch applied cleanly.

Thanks,
Hannes
