Spring Boot (Legacy) with GAE - Autowiring

[Rey Pader via StackOverflow]

I'm trying to make spring-boot-legacy:1.0.1.RELEASE & spring-boot-starter-parent:1.1.8.RELEASE with GAE 1.9.19. However, upon running via mvn appengine:devserver, I get the following error that prevents the app from running:

[INFO] java.lang.NoClassDefFoundError: java.lang.reflect.Parameter is a restricted class. Please see the Google  App Engine developer's guide for more details.

From what I understand, Spring uses reflection to auto-wire dependencies but it seems certain classes in the java.lang.reflect package are restricted. Any ideas on how to make this work?

java.lang.reflect.Parameter is used by Spring under Java 8. So you have to downgrade to Java 7 to stop using it. Another reason for this is that Google Appengine doesn't have support for Java 8, only Java 7. So you need it anyway.
