i have a project that uses ant. Ant produces a manifest file. This worked always well until yesterday: When i started my signed jar java told me, that the manifest contains an invalid field, but did not tell me which one. After hours of looking into my code and project, i found the error:

What can i do to let ant create a correct line break?
