Problem after updating jahia 4.0.2 to 4.0.3

[Philippe Van Der Gucht]

Hello,
Our jahia server went dead :(
The error in the logs:
java.lang.NoSuchMethodError: 
org.jahia.registries.ServicesRegistry.getCacheServerService()Lorg/jahia/services/htmlcache/CacheServerService;

I tracked down the offending line of cade in the generated java code from the jsp:
---8<---
// since we have made modifications concerning this page, let's flush
// the content cache for all the users and browsers as well as all
// pages that display this containerList...
ServicesRegistry.getInstance().getCacheServerService().removeEntry(Integer.toString(jPar
ams.getPageID()));
---8<---
Anybody have a clue?
Philippe.
