[jira] [Commented] (COMPRESS-447) ArrayIndexOutOfBoundsException in
ZipFile
[ https://issues.apache.org/jira/browse/COMPRESS-447?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16440813#comment-16440813 ]
Stefan Bodewig commented on COMPRESS-447:
-----------------------------------------
We've had some similar discussion at the end of COMPRESS-432 - it is unclear to me what the alternative to allowing the AIOBE bubbling up is. The file simply is not a valid ZIP archive when this happens.
Most likely throwing a {{ZipException}} would be more appropriate.
