[xwiki-devs] [VOTE] ScriptServiceManager#get should never throw exception

Hi devs, Right now it's pretty dangerous to manipulate script services from Velocity. If even you try to get a service that does not exist that will produce an exception which will kill your script for good. It's a pain to have use case like using a service only if it's here and fallback on something else otherwise. For example even if you disabled CSRF XWiki will fill in many places if you even think or removing the csrf jar. That seems pretty bad to me. The exception does not bring much value to scripts here (even for scripts supporting it) so I proposed to return null instead of throwing an exception. WDYT ? Here is my +1. -- Thomas Mortagne
