RFR: 8193682: Infinite loop in ZipOutputStream.close() [v11]

[Ravi Reddy]

> Hi all,
> 
> Please review this fix for Infinite loop in ZipOutputStream.close().
> The main issue here is when ever there is an exception during close operations on GZip we are not setting the deflator to a finished state which is leading to an infinite loop when we try writing on the same GZip instance( since we use while(!def.finished()) inside the write operation).
> 
> Thanks,

Ravi Reddy has updated the pull request incrementally with one additional commit since the last revision:
