[jira] [Commented] (MTOMCAT-215) Multiple manifests under META-INF,
two Main-Class entries
[ https://issues.apache.org/jira/browse/MTOMCAT-215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13599206#comment-13599206 ]
Tim Astle commented on MTOMCAT-215:
-----------------------------------
There are also multiple LICENSE and NOTICE files under the META-INF, but I was less concerned about those as I can't see those causing any potential technical issues. Worst case, on unzip, those files are overwritten or renamed.

> When using the -standalone jar / war mojos and looked into the artifact that they produced, I noticed that the META-INF directory contained mulitple MANIFEST.MF entries. I know that the zip archive format supports this, but I'm worried that it may produce undesirable behaviour as two of the manifest entries define a Main-Class. I'm uncertain how a winner is determined when -jar is the only option provided via command line.
> Additionally, for users who unzip an archive to make modifications, they could potentially blow-away the desirable manifest when manifests are overwritten to the same location on disk, thus crippling the executable jar / war functionality.
