GAE local debugging of Spring application

[Andrey Hudyakov]

Hi everyone,

I've developed a web application based on Spring Framework 4 and local debugging had worked fine on Java 7 but after migrated to Java 8 I've got an exception on startup

SEVERE: Context initialization failed

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

May be someone had the same issue and know how to solve it?

Hello, are you developing using Maven? If so, could you please try to update it to the latest release? Doing so has resolved this issue for others.

[Andrey Hudyakov]

Hello, Yannick!

Yes, I use maven. Updated to the latest version of Spring Framework 4 and still getting the same error. I forgot to say that this application works fine in Google Cloud after deploy. The problem is reproducing only when starting app in local debug mode. I use Google App Engine SDK 1.9.60.

Thank you for help!

Hello Andrey, to clarify I meant that Maven itself should be updated.

[Andrey Hudyakov]

Updating Maven and Java 8 to the latest versions didn't help also. Still getting the same error.

I recommend that you upgrade your App Engine SDK to the latest version (1.9.63) and if the issue still persists, open a case in Public issue Tracker. Meanwhile, you may migrate to the Cloud SDK-based Maven plugin which should address this issue.
