RFR: 8278794: Infinite loop in DeflaterOutputStream.finish() [v3]

[Ravi Reddy]

> Hi All,
> 
> This review request contains fix for infinite loop issue in DeflaterOutputStream.finish() in an exception scenario.
> 1. The issue is with 'finished' flag not getting set to correct value when there is an IOException in 
>     DeflaterOutputStream.finish() which will result in Infinite loops for next write operations on the same deflater.
> 2. Tighten the condition(to close deflater) in ZipOutputStream using an already existing 'finish' flag in Deflater class.
> 3. Added Inflater exception scenarios also to the test case, renaming test case to CloseInflaterDeflaterTest.java from CloseDeflaterTest.java
> 
> Thanks,
> Ravi
