Desktop Technologies: ZipException When Web Start is Downloading JAR file

We are experiencing a problem when we try to download our Java Web Start app remotely from the server using HTTPS.

It works fine when using HTTP.

There are a couple of JAR files that need to downloaded.

But, when using HTTPS it will choke on random JAR files and will toss the

following exception:

JNLPException[category: Download Error : Exception: java.util.zip.ZipException: error in opening zip file : LaunchDesc: null ]

at com.sun.javaws.cache.DownloadProtocol.doDownload(Unknown Source)

at com.sun.javaws.cache.DownloadProtocol.getResource(Unknown Source)

at com.sun.javaws.LaunchDownload.downloadJarFiles(Unknown Source)

at com.sun.javaws.LaunchDownload.downloadEagerorAll(Unknown Source)

at com.sun.javaws.Launcher.downloadResources(Unknown Source)

at com.sun.javaws.Launcher.handleApplicationDesc(Unknown Source)

at com.sun.javaws.Launcher.handleLaunchFile(Unknown Source)

at com.sun.javaws.Launcher.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

Does anyone have any ideas of what we might be bumping into here?

Any ideas for a fix or workaround?

I've search the bug database and the one that is matches most closely

is 6194024 but that does not target HTTPS specifically.

Any help would greatly be appreciated.

Thanks,
