After changing RCP from 3.6 to 4.4.2, NullPointerException is thrown, while removing ContributionItem from CoolBarManaer in WorkbenchWindowAdvisor.postWindowOpen() , Same code was working fine in 3.6.
Code used to remove ContributionItem
ICoolBarManager coolBarManager = getWindowConfigurer().getActionBarConfigurer().getCoolBarManager();
IContributionItem removedItem = coolBarManager.remove(contributionItem);
StackTrace
java.lang.NullPointerException
