Frustrated with Latest Java Version, Spring Context does not load - spring

Question

Thanks in advance to any one who reads this and can help.
I have an existing code base that I have to update to Java8, it runs in AWS EB. So I am trying to run it under a Java8 + Tomcat8 ami. When the app starts up, Spring throws an error on init:
Caused by: org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'config' defined in ServletContext
resource [/WEB-INF/spring/servlet-context.xml]: Invocation of init
method failed; nested exception is java.lang.IllegalArgumentException:
The resource path [META-INF/MANIFEST.MF] is not valid
Maven Generated Manifest file looks like this:
Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Built-By: mgriffith-contractor
Build-Jdk: 1.7.0_71
artifactId: quirinus
build-id:
build-number:
build-tag: 2.0-${BUILD_NUMBER}
build-time: 2015-03-25_18-40-13
groupId: com.zappos
version: 2.0
This error does not show up when the code is compiled and run under Java 7 using Tomcat8.
Google is not being cooperative -- so if you can offer any insights, any/all replies are appreciated.
** Edit **
I've also tried setting the target to 1.7. Compiled with Java 8, deployed to a Java8 JVM and Tomcat 8 AMI the entire stack looks like this:

Answer 1

So it turns out that a dependency was trying to read the Manifest file by referencing Jarfile.MANIFEST -- which evidently needs to be
/META-INF/MANIFEST.MF
in Java 8 instead of
META-INF/MANIFEST.MF
in previous versions...
