javax.management.MBeanServerFactory é uma classe restrita

Question

Estou tentando fazer o Spring Boot funcionar com o GAE, mas quando executo appengine:devserver o aplicativo lança:

[INFO] Jun 03, 2014 11:43:26 AM com.google.apphosting.utils.jetty.JettyLogger warn

Como contornar esse problema?

Answer 1

Eu implantei este aplicativo ontem para o GAE (do master) e está funcionando bem (nenhum sinal do problema do logger que você estava tendo).Então qual é a diferença?Também tive que fazer algumas alterações no Boot master, mas nunca vi os problemas da classe não encontrada que você faz.

Answer 2

A linha "java.lang.NoClassDefFoundError: javax.management.MBeanServerFactory is a restricted class. Please see the Google App Engine developer's guide for more details." na sua mensagem de erro é devido à restrição do mecanismo de aplicativos do Google.

Referência

O App Engine não permite que seu aplicativo acesse javax.management.* .
