Description vincent_daniels 2014-03-25 13:20:21 UTC 
+++ This bug was initially created as a clone of Bug #45628 +++

Deploying webapps that contain commons-attributes-api.jar or commons-attributes-compiler.jar (downloaded from the Maven repository) fail with a message from ExtensionValidator along the lines of 'Required extension "ant" not found'. 

. . .

Bug #45628 claims this was fixed in Apache 5.5.? and 6.0, but I'm using 7.0 and have this exact condition which keeps my context from running.  

INFO: ExtensionValidator[][commons-attributes-api-2.2.jar]: Required extension [ant] not found.

Just like bug 45628, there is no issue handling wrapped lines in manifest files. The error message is valid and correct.

The extensions defined in the common-attributes-api.jar, on the other hand, looks to be invalid. The specified extension name doesn't match the extension name used in the Ant JARs.
