Installation of hotfixes or marketpace packages fails because of class "org.eclipse.core.runtime.MultiStatus"'s signer information

[Solen_Guitter]

For instance, when I try to install the hotfix 7 for 5.6, I get an error message that says:

Installation failed : class "org.eclipse.core.runtime.MultiStatus"'s signer information does not match signer information of other classes in the same package.

How can I install the hotfix?

To workaround this issue:

1. After stopping the Nuxeo server, remove org.eclipse.equinox.common-3.6.0.v20100503.jar from nxserver/lib/.
2. Put the org.eclipse.equinox.common-3.6.0.v20100503.jar file attached NXP-10279 in nxserver/lib/.
3. Start your server.

You can now install any hotfix or Marketplace package from the Admin Center or using nuxeoctl mp-install.
