4.0.0 bug multiline-manifest-value-bug jar 2 Test case for valid multiline manifest values. Maven will set manifest values to illegal multiline values. This module has this multiline description attribute, which if included directly in the manifest will make a corrupt manifest. To use this test, package this POM and then inspect the manifest: Maven will use this value literally as the Jar's "Specification Title", and the Jar will be corrupt.
