> I tried to extract three gz files, and they are corrupt. The two of them at ahead  throw the IOExceptions:
> Caused by: java.io.IOException: Gzip-compressed data is corrupt
> 	at org.apache.commons.compress.compressors.gzip.GzipCompressorInputStream.read(GzipCompressorInputStream.java:253)
> 	at java.io.InputStream.read(InputStream.java:82)
> ...
> But when comes to the third one it throw out OOM as below:
> java.lang.OutOfMemoryError
> 	at java.util.zip.Inflater.inflateBytes(Native Method)
> 	at java.util.zip.Inflater.inflate(Inflater.java:238)
> 	at org.apache.commons.compress.compressors.gzip.GzipCompressorInputStream.read(GzipCompressorInputStream.java:251)
> 	at java.io.InputStream.read(InputStream.java:82)
> The third file is corrupt, but Linux recognize it as a compressed gz file.
> More info:
