Signing jars for Eclipse 3.6.x or higher [message #1740246]

Hello to the forum members,

I'm developing a plugin for an Eclipse product. It has two instances, one supports Eclipse 3.6.x and the other 4.2.x. I'm using signjar ant task to sign my plugin and feature. When I try to install it on Eclipse I keep getting "Error reading signed content" error. Doing some digging in Eclipse source and on the web I found the following links:
https://dev.eclipse.org/mhonarc/lists/cross-project-issues-dev/msg11770.html
https://bugs.eclipse.org/bugs/show_bug.cgi?id=378155

So, I understand there's an issue with Eclipse 3.6 and signing jars with Java 1.7. I'm using IBM Java 1.6 and I still get this error.

By the way the signjar task outputs the following:
[signjar] Warning:
[signjar] Using SHA-1 digest algorithm for timestamp generation. See the -tsadigestalg option.

Any ideas how to fix this ?

Thanks,
Gidi

An update: I found out that a work-around would be to perform the signing process with Java 1.5 and Eclipse 3.5. I'm still looking for a solution, preferably for Java 1.7.

Also, the link below describes work-around of setting the signatures on the update site instead of the jars. If anyone has a link that explains this process and whether it requires changes in workflow for the user, I'll be grateful if you could share it here.
