Issue

• Eclipse/JBDS progress is doing many stuff when designing SwitchYard application and especially while adding a new Camel Component (XML) for example or just doing changes and saving them. How can users reduce the time of background processing or stop them at all? Inside the Eclipse/JBDS workspace folder's /.metadata/.log file following exceptions could be seen being logged. How to fix them and what causes them?

• Is there anyway to disable the access of those plugins which are causing the delay in performing any action in Eclipse/JBDS at background?
