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.
