Konrad Windszus updated MSHARED-815: ------------------------------------ Description: According to https://docs.oracle.com/javase/10/docs/specs/jar/jar.html#name-value-pairs-and-sections {quote} Groups of name-value pairs are known as a "section". Sections are separated from other sections by empty lines. {quote} Therefore empty lines in attribute values lead to invalid manifests and must somehow be escaped. As this is not done by default in {{java.util.jar.Attributes.writeMain(...)}} the method {{MavenArchiver.addManifestAttribute(...)}} should either throw an exception in case of empty lines given to parameter {{value}} or escape those empty lines somehow (https://github.com/apache/maven-archiver/blob/d454ab3fcd147c0201a14f298cc8f9e1a25ba03e/src/main/java/org/apache/maven/archiver/MavenArchiver.java#L221). was: According to https://docs.oracle.com/javase/10/docs/specs/jar/jar.html#name-value-pairs-and-sections {quote} Groups of name-value pairs are known as a "section".
