Hi,

I have an Eclipse EMF based application. It runs well in may AppEngine Eclipse 
testing env. However, when it is deployed to the cloud, I get the following 
error:

Caused by: java.lang.SecurityException: SHA1 digest error for 
org/eclipse/emf/ecore/EObject.class

The same application ran well in previous AppEngine version. It seems that the 
AppEngine security control has been changes.

Anyone can explain the reason? Also, the difference between AppEngine Eclipse 
testing env and the real Java running env in the cloud would be appreciated.

Thanks, Mike
