RFR 8161426: Test java/util/zip/InflaterInputStream/TestAvailable.java fails on open-only linux

[Xueming Shen]

Brian,

Would you please help review the change for JDK-8161426. The test case
I pushed back yesterday fails in corner case when the Random.nextInt(n)
returns 0, in which we have a 0-length data/src byte[].

issue: https://bugs.openjdk.java.net/browse/JDK-8161426
webrev: http://cr.openjdk.java.net/~sherman/8161426/webrev

Thanks,
Sherman
