             Summary: Naive OOM when deal with a corrupt .gz file
                 Key: COMPRESS-248
                 URL: https://issues.apache.org/jira/browse/COMPRESS-248
             Project: Commons Compress
          Issue Type: Bug
          Components: Compressors
    Affects Versions: 1.6
         Environment: Fedora 19 x86_64, 8G RAM, Java version "1.7.0_45"
OpenJDK Runtime Environment (fedora-2.4.3.0.fc19-x86_64 u45-b15)

            Reporter: Jing Li


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:

[jing@localhost logs]$ file stdout.log.txt.gz 
stdout.log.txt.gz: gzip compressed data, was "stdout.log_backup", from Unix, last modified: Tue Nov 19 22:53:19 2013
[jing@localhost logs]$ tar -xvzf stdout.log.txt.gz

gzip: stdin: invalid compressed data--format violated
tar: Child returned status 1
tar: Error is not recoverable: exiting now
